Protein Biofertilizer Development and Application on Soybean Cultivated Degraded Soil

This paper addresses the priority area of greening tanneries by recovering hide waste as fertilizing biocomposites. The paper presents the development of protein biofertilizers and their application in agriculture for plant growth and remediation of nutrient-poor soil. The aim was to obtain protein biofertilizers and apply them to soybean crop having the effect of stimulating the metabolism, speeding the productive phase, stimulating the defense system of the plant. We also obtained healthy plants and increases in production quality upon application of fertilizing biocomposites based on collagen hydrolysate. The highest increase of production was recorded for variants to which the protein biofertilizer was applied before sowing.
