Lupin SIDERAT 46

Biological Optimization of Soil Profiles

The «Siderat 46» lupine, developed by the V.R. Williams All-Russian Research Institute of Forage, is a specialized tool for intensive organic farming. The primary objective of this variety is the rapid accumulation of organic matter and nitrogen within the root zone.

Technical Development Parameters

The genetic potential of the variety allows for the development of robust vegetative biomass ranging from 80 to 150 cm in height. Under agro-ecosystem conditions, this provides significant weed suppression through effective soil shading. With a seeding rate of 150–200 kg/ha, the variety demonstrates a high tillering coefficient, producing green biomass yields of 30–50 t/ha. This volume of organic material not only provides physical soil structuring but also contributes to substantial enrichment in organic carbon.

Nitrogen-Fixation Efficiency

A critical technical metric for «Siderat 46» is its protein content in dry matter, which stands at 15–20%. From a technical perspective, this signifies a high capacity for biological nitrogen sequestration. When incorporated into the soil, the mineralization of nitrogenous compounds occurs, making nutrients readily available for subsequent crops in the rotation. The plant functions as a “green manure” with an efficacy comparable to significant applications of synthetic nitrogen fertilizers, simultaneously improving soil aeration and hydraulic conductivity through its deep taproot system.

Practical Applications

• Crop Rotation Optimization: A short development cycle allows for use both as a cover crop and a primary green manure for soil reclamation.
• Soil Structuring: Powerful taproots penetrate dense soil horizons, decompacting them without mechanical intervention.
• Phytosanitary Impact: Rapid biomass accumulation reduces the necessity for herbicide applications on the plot.
