A recent meta-analysis determined that biochar addition to coarse, medium, and fine-textured soils increased available water by 45%, 21%, and 14%, respectively, confirming the general trend described above. Studies focusing on biochar and hydraulic conductivity have found similar results related to available water with biochar additions resulting in reduced hydraulic conductivity in sandy soils. The mechanism is related to biochar particles retaining more water internally in the micropores, thereby increasing the available water reserve for plant roots in coarse-textured soils. In clay soils, biochar additions tend to increase hydraulic conductivity and field capacity simultaneously, while reducing soil bulk density, resulting in improved drainage, porosity, and plant available water.

The application of PURAENVIRO AGRO biochar gives even superior results.

Benefits:

Better aeration
Better water retention
Greater infiltration

PURAENVIRO AGRO biocatalyst (or biostimulant) is a unique liquid blend of organic acids, phenols, and natural compounds. While the biochar provides shelter for beneficial microbes, the biocatalyst (or biostimulant) stimulates them, allowing for significant improvements in nutrient uptake and yield.

The organic acids present in the PURAENVIRO AGRO biocatalyst, specifically acetic, malic, lactic, and succinic acids, play a fundamental role in the solubilization and mobilization of essential minerals such as iron (Fe), phosphorus (P), potassium (K), and magnesium (Mg). These organic acids form complexes with key minerals, thereby improving their availability and accessibility to plants.

Benefits:

greater accessibility to nutrients
