Depositional seals in polyacrylamide-amended soils of varying

Purpose Depositional seals, formed when turbid waters infiltrate into soils, lead to a reduction in soil hydraulic conductivity (HC) and enhance runoff and soil erosion. Since clay size particles constitute a dominant proportion of depositional seals, soil texture and clay mineralogy play a significant role in determining the seal’s hydraulic characteristics. Presence of high molecular

We evaluated four treatments: a compacted soil (C), a compacted soil with core aeration (A), a compacted soil with deep (20 - 30 cm) tillage (DT), and a compacted soil with deep tillage and incorporated compost (CT). Sites 1 and 2 received C, A and DT treatments and Site 3 received only DT and CT treatments.

Development of fertilizers for enhanced nitrogen use

When the product was amended in a near-neutral (pH 6.3) clay soil, significantly less nitrate was recorded over time, compared to urea at the same N application rate of 200 kg/ha. A delayed nitrification process (≈29 days) was observed for the organically enhanced fertilizer, compared to urea (≈5 days).

Soil enzyme activities are often used as indices of microbial function and soil fertility (Dick & Tabatabai, 1992; Kumar et al., 1992) and are considerably affected by the quality and quantity of root exudates depending on the plant species, cultivar, plant growth stage and physiological status of the plant (Saxena et al., 1999).
