- Abstract:
- ... Groundwater (GW) is a vital source of water supply for drinking, irrigation, and industry in most parts of India. In Punjab, the adoption of the rice-wheat cropping system has led to a manifold increase in the irrigation water demand, and about 73% of it is met from GW. Consequently, the GW level in the state is declining rapidly due to its overuse and misuse. To conserve irrigation water, the Gov ...

- Abstract:
- ... Rice is predominantly grown on puddled soils (puddling is achieved through wet tillage in ponded water to create a soft soil environment and impermeable sub-soil layer) in the Eastern Gangetic Plains (EGP) of Bangladesh. Puddling is often discouraged while practicing conservation agriculture (CA) to achieve maximum system benefit. Zero-till unpuddled transplanted rice (ZT UPTR) could be a good sub ...

- Abstract:

In the mid-Atlantic USA region, nitrogen uptake by crops ceases about four weeks prior to harvest maturity, leaving substantial mineral N in the soil profile, which is prone to leach during the winter. Deep-rooted cover crops planted by early-September can potentially take up residual N and recycle some of it for following cash crops. We performed experiments on 19 minimum-tillage, grain farms inv ...

- Abstract:
- ... Soil organic carbon (SOC) is important natural capital for agricultural production, as it affects soil physical, chemical and biological functions and the provision of ecosystem services. Measures of land-use effects on SOC stocks generally focus on the top 0.3 m of soil, as the topsoil has the highest SOC concentration. However, while subsoil horizons have low SOC concentrations, they contain a g ...

However, it is expensive to sample and directly measure across a heterogenous field and at different depths. To add value to limited data, proximally sensed apparent soil electrical conductivity (ECₐ, mS m⁻¹) from electromagnetic (EM) instruments has been coupled to CEC at each depth t ...

For example, tax revenues can be large and highly volatile, and the stream of revenues is finite. An increasing number of countries now view resource funds and/or fiscal rules for resource revenues as the answer to these challenges. In this paper, we explore the consequences for th ...

Podzolization imparts soils and landforms of the southeastern United States Coastal Plain with two distinct pools of organic carbon (C), referred to as shallow podzolized C (SPC) and deep podzolized C (DPC). We evaluate podzolization across two catenas, and across the state of Florida, to establish that SPC and DPC are morphologically and hydrologically distinct. We demonstrate that SPC lightens d ...

Wetting of dry soil triggers a pulse of microbial respiration that has been attributed to two broad mechanisms: (1) recycling of microbial cellular carbon (C), and (2) consumption of extracellular organic C made available to microbes by wetting. We evaluated these two mechanisms by measuring cumulative CO₂ release, changes in the size and chemical composition of microbial biomass, and water-extrac ...
