This article presents a three-year (2021–2023) comparative study of the effects of FAO-56-scheduled drip irrigation versus conventional furrow irrigation on soil agrochemical properties. In cooperation with the Jizzakh Branch of the Agrochemical Station of “O’ZAGROKIMYOHIMOYA” JSC, changes in humus, available phosphorus (P₂O5), available potassium (K₂O), and total nitrogen (N) content were studied according to GOST 26213-91 and GOST 26205-91 standards. Comparing indicators from early 2021 to late 2023 at the experimental site in the Sharof Rashidov district, drip irrigation increased humus content by 0.17 %, available phosphorus by 9.3 mg/kg, and total nitrogen by 0.008 %, while the rate of available potassium depletion was nearly half that observed under furrow irrigation.
Intensive agriculture based on monocultures leads to ecological crises due to high resource consumption, agrochemical pollution of soil and groundwater, and negative impacts on climate change. As an alternative solution to this problem, breeding perennial wheat lines and creating sustainable agrosystems are of high imp...

The baseline agrochemical condition Of irrigated meadow soils was analyzed, focusing on the patterns of vertical distribution of humus, as well as total and available nutrients (nitrogen, phosphorus, potassium) along the 0–100 cm profile. The results show that in the upper arable layer (0–30 cm), the content of humus i...
