After harvesting agricultural crops, the residue can be returned to soil as mulch. This study performed a meta-analysis of previous research investigate effects crop return and other factors on yields water use efficiency (WUE). Overall, results show that increases by 5.0% relative crops grown without it. The greatest in yield for with were associated average annual temperatures < 10 °C (yield increase = 7.6%), rainfall ≥ 800 mm (9.5%), plowing depth 20 cm (6.5%), corn (8.0%), growth single per year (10.1%), no irrigation (11.9%), nitrogen (N), potassium (K) fertilization (20.0%), low application rates 0–100 kg N ha-1 (10.8%). found vary according following properties: organic matter content 15 g kg-1 9.4%), available 100 mg (10.3%), pH ≤ 6.5 (11.2%). magnitudes WUE 13.7%), medium (100–150 ha-1; 23.3%), high (≥ kg-1; 25.5%) air (< °C; 19.9%).

Conservation Agriculture Effects on Soil Water Holding Capacity and Water-Saving Varied with Management Practices and Agroecological Conditions: A Review

Agronomy, Год журнала: 2021, Номер 11(9), С. 1681 - 1681

Improving soil water holding capacity (WHC) through conservation agriculture (CA)-practices, i.e., minimum mechanical disturbance, crop diversification, and mulch cover/crop residue retention, could buffer resilience against climate change. CA-practices increase organic carbon (SOC) alter pore size distribution (PSD); thus, they improve WHC. This paper aims to review what extent can influence WHC water-availability SOC build-up the change of PSD. In general, sequestered due adoption CA does not translate into a significant in WHC, because is limited top 5–10 cm, which limits whole profile.

Carbon sequestration potential, challenges, and strategies towards climate action in smallholder agricultural systems of South Asia

South Asia is a global hotspot for climate change with enormous pressure on land and water resources feeding the burgeoning population. The agricultural production systems are highly vulnerable in region primarily dominated by small marginal farmers intensive farming practices that had favored loss of carbon (C) from soil. This review discusses potential soil crop management such as minimum/reduced/no-tillage, use organic manure, balanced integrated plant nutrient application, precision levelling, pest management, residue cropping system optimization to maintain C-equilibrium between atmosphere enhance C-sequestration long run. Results meta-analysis show 36% increase C stock top 0–15 cm layer this which amounts ∼18 Mg stocks ha−1. Improved across crops environment may reduce methane em0ission 12% resulting an 8% reduction warming (GWP), while non-submerged condition led 51% GWP rice.

Although several innovative resilient technologies having significant have been developed, there urgent need their scaling accelerated adoption C-sequestration.
