Adoption of a biologically-enhanced agricultural management (BEAM) approach in agroecosystems for regenerating soil fertility, improving farm profitability and achieving productive utilization of atmospheric CO₂.

ABSTRACT:

Background

A 4-year field study, on the adoption of a Biologically-Enhanced Agricultural Management (BEAM) protocol, in a cotton/cover-crop rotation in Turkey, was designed to observe "change-over-time" of soil organic carbon (SOC%) and total soil nitrogen (TSN%) at three soil profile depths (0-15 cm, 15-30 cm and 30-45 cm) while tracking farm productivity and profitability.

Methods

BEAM systems employ regenerative practices: (a) no-till, (b) no, or reduced synthetic nutrient amendments, (c) continuous roots in the ground (commodity/cover), accompanied with an injection (in-furrow at planting) of an extract of beneficial microbes, from a Johnson-Su bioreactor. Three field nitrogen treatments: (1) BEAM+100% N (203 kg N ha^-1); (2) BEAM+15% N (30.53 kg N ha^-1
