Globally, the expansion of agriculture occurs in a scenario of increasing demand for fertilizers and depletion of natural resources, which requires alternative and economically viable sources of nutrients, actions that sustain the <a href=\"https:\/\/ilsabrasil.com.br\/en\/economia-circular-e-sustentabilidade-nos-processos-da-ilsa\/\">circular economy<\/a> (Velenturf et al., 2019). The use of industrial by-products in agriculture emerges as a strategy to reduce waste disposal into the environment, in addition to providing an alternative source of nutrients for plants and possibly reducing costs with the application of mineral fertilizers (Lima et al., 2010; Coelho et al., 2015).<\/p>\n<p><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong>The reuse of leather-derived waste is a pressing issue within the circular economy and represents an important step towards the sustainability of the tanning industry (Chojnacka et al., 2021). Rawhide or treated leather waste can contain up to 10.5% of protein per dry weight, which can be hydrolyzed to obtain collagen as a raw material for the production of organic fertilizers or soil amendments (Nogueira et al., 2011; Oliveira-Longatti et al., 2017; Majee et al., 2021). The organic matrix of fertilizers containing the by-product of the intermediate tanning process (BPIPT) derived from the transformation of collagen from hides and skins is homogeneous.<\/p>\n<p><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong>BPIPT can have high N contents (up to 140 g kg<sup>-1<\/sup> N by dry weight) and in combination with other nutrients can be used to produce smart fertilizers (Majee et al., 2021; Stefan et al., 2021). These products can complement or replace the application of mineral N fertilizers (e.g., urea), increase nutrient use efficiency (NUE) (Nogueira et al., 2011; Ciavatta et al., 2012), increase N mineralization and microbial activity (Oliveira-Longatti et al., 2017), and lead to increased biomass and crop yield (Lima et al., 2010; Coelho et al., 2015; Majee et al., 2021).<\/p>\n<p><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong>Given the importance of using fertilizers produced with a by-product of the intermediate tanning process, the work aimed to:<\/p>\n<ul>\n<li>Evaluate the chemical and biological properties of the soil after the application of organomineral fertilizers formulated with the AZOGEL \u00ae matrix;<\/li>\n<li>To evaluate the impacts of such products on wheat growth and nutrition.\n<p>Note: It is important to note that this trial was conducted for regulatory purposes and the results presented here were <strong>adapted<\/strong> from the original in order to demonstrate the effect of the organic matrix AZOGEL \u00ae on the parameters mentioned above.<\/li>\n<\/ul>\n<p><strong>MATERIAL AND METHODS<\/strong><\/p>\n<p><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong>Soil samples were collected from the 0\u20130.2 m layer of a native area (native Cerrado vegetation) located in the Campo das Vertentes region, Minas Gerais, Brazil. According to the Brazilian Soil Classification System (Santos et al., 2018), soils were classified as typical dystrophic Red-Yellow Latosol (LVAd) and typical dystrophic Red Latosol (LVd), corresponding to Latosol in the USDA Soil Taxonomy (Soil Survey Team, 2014). Physical and chemical properties were determined in air-dry fine earth (ADFE; &lt;2 mm) (Table 1).<\/p>\n<p><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong>Soil samples were dried, crushed, and passed through a 4-mm sieve tube. Then, the samples were homogenized and stored in plastic bags. A mixture of calcium (Ca) and magnesium (Mg) carbonates in a molar ratio of 3:1 (Ca:Mg) was used to increase soil pH and base saturation to 60%, in agreement with previous soil analyses (\u00c1lvarez and Ribeiro, 1999). The soil was incubated at room temperature for 60 days with soil moisture maintained at field capacity. Soil samples were homogenized once a week during the incubation period.

The sources of inorganic fertilizers (commercial sources) used to supply N, P and K were, respectively, urea, monoammonium phosphate (MAP) and potassium chloride (KCl).

Daily irrigations were performed to maintain soil moisture at field capacity. After seven days, the seedlings were thinned to only seven plants per pot. The experiment was conducted for 30 days in a greenhouse, with controlled temperature and air humidity.

Normality and homoscedasticity of the data were assessed. Analysis of variance (p \u00ff 0.05) was used to verify the significance of the treatments. Then, the treatments were compared using the Tukey HSD test with the emmeans package v1.4 (Length, 2020). Principal component analysis (PCA) was performed using the Vegan package v2.5-7 (Oksanen et al., 2016) to demonstrate the importance of the variables in explaining the nutrient content and biomass increase of wheat plants.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>RESULTS<\/strong><\/p>\n<p><strong>1st Stage<\/strong><\/p>\n<p>The P and K contents increased in both soils after FOM application (Figure 1). It was possible to note that this greater availability of elements \u2013 nutrients \u2013 was beneficial for wheat development and soil biological activity. Fertilizers based on tannery byproducts have shown many benefits to soil attributes and plant production. They present increased C and N contents in their composition (Ciavatta et al., 2012; Majee et al., 2021) and gradual release of N (Lima et al., 2010), which optimizes the use of nitrogen fertilizers by crops. This greater efficiency in N use can result in higher yields (Castilhos et al., 2002; Coelho et al., 2015) and lower soil acidity (Ferreira et al., 2003; Teixeira et al., 2006). Thus, the use of BPIPT for the production of FOM favors a circular economy (Chojnacka et al., 2021), as the by-product is incorporated into a different productive sector, that is, from the tanning industry to agriculture.<\/p>\n<p><img decoding=\"async\" class=\"alignnone  wp-image-9415\" src=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-300x109.png\" alt=\"\" width=\"454\" height=\"165\" srcset=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-300x109.png 300w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-1024x371.png 1024w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-768x278.png 768w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-100x36.png 100w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-220x80.png 220w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-255x92.png 255w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-85x31.png 85w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01-140x51.png 140w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-01.png 1423w\" sizes=\"(max-width: 454px) 100vw, 454px\" \/><\/p>\n<p>Figure 1 \u2013 P and K contents extracted by Mehlich-1 in typical dystrophic Red-Yellow Latosol (LVAd) and typical dystrophic Red Latosol (LVd) after incubation of FOM containing the AZOGEL \u00ae matrix (mean \u00b1 SE, n = 5).<\/p>\n<p>Microbial biomass carbon (MBC) increased with the addition of OMF, which reflects greater soil biological activity (Figure 2). With the addition of OMF, it was possible to observe that there were increases in the availability of resources, carbon, and nutrients for the microbiota, which favored the increase in MBC and microbial activities, even in a short experimental period. This effect was probably due to the increased availability of nutrients and energy for the microbial community in this soil. Tannery by-products are rich in proteins and lipids, which represent a promising source of nutrients, as they can stimulate the decomposition and mineralization activities of the soil heterotrophic community, providing nutrients for plants and microorganisms (Majee et al., 2021). What makes the reuse of this residue an environmentally friendly activity is that, in addition to disseminating the concept of circular economy in the industry (Velenturf et al., 2019), it is also a source of multi-element fertilizers for plants and microorganisms.<\/p>\n<p><img decoding=\"async\" class=\"alignnone  wp-image-9416\" src=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-300x185.png\" alt=\"\" width=\"358\" height=\"221\" srcset=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-300x185.png 300w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-768x475.png 768w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-100x62.png 100w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-220x136.png 220w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-255x158.png 255w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-85x53.png 85w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02-140x87.png 140w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-02.png 982w\" sizes=\"(max-width: 358px) 100vw, 358px\" \/><\/p>\n<p>Figure 2 \u2013 Microbial biomass carbon (MBC) in a typical dystrophic Red-Yellow Latosol (LVAd \u2013 A, B and C) and a typical dystrophic Red Latosol (LVd \u2013 D, E and F) after incubation of FOM containing the AZOGEL \u00ae matrix (mean \u00b1 SE, n = 5).<\/p>\n<p>The FDA analysis better reflected the effects of FOM application in both soil types, while the enzyme <a href=\"https:\/\/ilsabrasil.com.br\/en\/bioanalises-e-a-importancia-dos-microrganismos-na-agricultura\/\">\u03b2 \u2013 glycosidase and arylsulfatase<\/a> showed variable behaviors (Figure 3). The application of FOM led to higher wheat yields and increased enzymatic activities in the soil. However, the activity of the arylsulfatase enzyme decreased after the application of FOM in the LVd (Figure 3), which may be related to a greater availability of S after the application of the products. This enzyme acts in some stages of the mineralization of organic S, and reductions in the activity of arylsulfatase may occur if inorganic S is present in these fertilizers. Oliveira Longatti et al.

Both soils showed a tendency for increased b-glucosidase and ADF activities after FOM application and higher wheat yields.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-9418\" src=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-300x72.png\" alt=\"\" width=\"681\" height=\"163\" srcset=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-300x72.png 300w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-1024x246.png 1024w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-768x184.png 768w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-1536x369.png 1536w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-100x24.png 100w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-220x53.png 220w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-255x61.png 255w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-85x20.png 85w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04-140x34.png 140w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-04.png 1558w\" sizes=\"(max-width: 681px) 100vw, 681px\" \/><\/p>\n<p>Figure 4 \u2013 General soil enzymatic activity (fluorescein diacetate hydrolysis \u2013 FDA) and b-glucosidase in typical dystrophic Red-Yellow Latosol (LVAd) and typical dystrophic Red Latosol (LVd) soils after wheat cultivation with organomineral fertilizers containing the organic matrix AZOGEL \u00ae (mean \u00b1 SE, n = 5).<\/p>\n<p>After planting wheat, treatments with FOM showed greater aerial part (SDM) and root (RDM) weight (Figure 6).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-9419\" src=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-300x113.png\" alt=\"\" width=\"465\" height=\"175\" srcset=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-300x113.png 300w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-1024x386.png 1024w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-768x290.png 768w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-100x38.png 100w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-220x83.png 220w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-255x96.png 255w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-85x32.png 85w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05-140x53.png 140w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-05.png 1500w\" sizes=\"(max-width: 465px) 100vw, 465px\" \/><\/p>\n<p>Figure 5 \u2013 Dry mass of aerial part (SDM), MSD and dry mass of root (RDM) of wheat in typical dystrophic Red-Yellow Latosol (LVAd) and typical dystrophic Red Latosol (LVd) after wheat cultivation with organomineral fertilizers containing the organic matrix AZOGEL \u00ae (mean \u00b1 SE, n = 5).<\/p>\n<p>&nbsp;<\/p>\n<p>The nutritional increase of macronutrients and micronutrients in the two types of soils used can be observed in figures 6 and 7. In wheat grown in LVAd, the P and K contents in SDM increased significantly in all treatments compared to the control. However, no difference was observed between FOM treatments. The Ca and Mg contents did not differ from the control. The SDM content was the highest for OM-ITP+S (3 g kg<sup>-1<\/sup>) and the lowest for the control (1.8 g kg<sup>-1<\/sup>).<\/p>\n<p>Overall, the application of FOM in LVAd increased micronutrient contents. Specifically, Mn had an average content of 36 mg kg<sup>-1<\/sup> in the control, and an average content of 225 mg kg<sup>-1<\/sup> for FOM treatments in LVAd. Overall, micronutrient contents in SDM increased after FOM addition. However, probably due to the buffering effect of the higher clay content of this soil, the increases in Mn and Zn contents were less pronounced when compared with LVAd.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-9420\" src=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-300x102.png\" alt=\"\" width=\"485\" height=\"165\" srcset=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-300x102.png 300w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-1024x350.png 1024w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-768x262.png 768w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-1536x524.png 1536w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-100x34.png 100w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-220x75.png 220w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-255x87.png 255w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-85x29.png 85w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06-140x48.png 140w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-06.png 1564w\" sizes=\"(max-width: 485px) 100vw, 485px\" \/><\/p>\n<p>Figure 6 \u2013 Macronutrient and micronutrient contents in typical dystrophic Red-Yellow Latosol (LVAd).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-9421\" src=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-300x97.png\" alt=\"\" width=\"498\" height=\"161\" srcset=\"https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-300x97.png 300w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-1024x331.png 1024w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-768x248.png 768w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-1536x496.png 1536w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-100x32.png 100w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-220x71.png 220w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-255x82.png 255w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-85x27.png 85w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07-140x45.png 140w, https:\/\/ilsabrasil.com.br\/wp-content\/uploads\/2023\/09\/figura-07.png 1557w\" sizes=\"(max-width: 498px) 100vw, 498px\" \/><\/p>\n<p>Figure 7 \u2013 Macronutrient and micronutrient contents in typical dystrophic Red Latosol (LVd).<\/p>\n<p>&nbsp;<\/p>\n<p><strong>CONCLUSIONS<\/strong><\/p>\n<p>The application of organomineral fertilizer (FOM) in the soils of the present study increased the growth, macro (P, K, Ca, Mg and S) and micronutrient (Cu, Fe, Mn, B, Zn) contents in wheat plants.<\/p>\n<p>This trend was more evident in the dystrophic Red-Yellow Latosol (LVAd), which presented lower clay and Fe oxide contents than the dystrophic Red Latosol (LVd) and, therefore, may be more responsive to changes in management practices. After wheat cultivation, the presence of S in the FOM led to soil acidification.<\/p>\n<p>Furthermore, the application of organomineral fertilizer (OMF) increases microbial biomass carbon (MBC) with increased addition of OMF, which reflects greater soil biological activity. With the addition of OMF, it was possible to observe that there were increases in the availability of resources, carbon and nutrients for the microbiota, which favored the increase in MBC and microbial activities.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Bibliographic references<\/strong><\/p>\n<p>Alef, K.
