Abstract The response of wheat to the application different rates nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) under balanced fertilization on soil types agroecologies has not been well studied in Ethiopia. Therefore, objectives this study were (1) determine soil-specific responses N, P, K, S fertilization; (2) quantify agroecology-specific (3) nutrient use efficiency fertilizati...
A field study was conducted during 2021-22 at the Research of All India Coordinated Project for Dryland Agriculture (AICRPDA), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, (Dr. PDKV) Akola, Maharashtra (India), on an ongoing long-term experiment initiated in 1987-88 under cotton + green gram (1:1) intercropping system Vertisols. The eight treatments comprised a control, sole use organics and chemi...
The Lower Mississippian (Tournaisian) Ballagan Formation in SE Scotland yields tetrapod fossils that provide fresh insights into the critical period when these animals first moved onto land. The key to understanding the palaeoenvironments where they lived is a detailed analysis of the sedimentary architecture of this formation, one of the thickest and most completely documented examples of a co...
Reduction of quality and soil productivity due to organic carbon losses is one of the most important consequences of land use changes, that creates irreparable effects on the soil. To evaluate the land use effect on the amount of soil organic carbon in Vertisols, Sartip Abad series with extent of 1850 hectare in south of Bilehvar area in Kermanshah province was studied by using the completely r...
Selenium is an essential element in human diets but the risk of suboptimal intake increases where food choices are narrow. Here we show that suboptimal dietary intake (i.e. 20-30 µg Se person(-1) d(-1)) is widespread in Malawi, based on a spatial integration of Se concentrations of maize (Zea mays L.) grain and soil surveys for 88 field sites, representing 10 primary soil types and >75% of the ...
Termites can play a localized prominent role in soil nutrient availability and cycling because mound materials are often enriched nutrients relative to surrounding soil. Mound may thus prove be useful amendments, though evidently spatial arrangement needs considered as well. Furthermore, it is not known if gradients of properties exist from termite interspace sites. Studying both aspects would ...
