Abstract:

For southern steppe regions of the country the soil protection technologies of crop production, being exemplified by chernozems in the Pre-Caucasus region have been elaborated and put into practice with the aim at increasing their productivity, fertility recovery and preventing the soils and crops against erosion processes. In the forest-steppe zone a set of soil protection measures including the contour organization of the territory, strip cropping, selection of soil amendment crops, soil biologization is used in agro-gray eroded soils on slopes (to 5º).

Abstract:

Agroindustrial grouping of soils is an important measure in terms of land subsidies, as well as increasing soil productivity, increasing their productivity and proper placement of crops on a scientific basis. In Azerbaijan, the agroindustrial grouping of soils is usually carried out in two groups on the basis of their genetically-production characteristics and scores of soil cover.

Abstract:

Salinity impedes soil and crop productivity in over 900 million ha of arable lands worldwide due to the excessive accumulation of salt (NaCl). To utilize saline soils in agriculture, halophytes (salt-tolerant plants) are commonly cultivated. However, most food crops are glycophytes (salt-sensitive). Thus, to enhance the productivity of saline soils, gypsum (CaSO4·2H2O) as well as bio-organic (combined use of organic materials, such as compost and straw with the inoculation of beneficial microbes) amendments have been continuously recognized to improve the biological, physical and chemical prop

There is evidence that the contribution of declining soil fertility to soil degradation has been underestimated. Sensitivity to soil degradation is implicit in the assessment of the sustainability of land management practices, with wide recognition of the fact that soils vary in their ability to resist change and recover subsequent to stress.

In addition to increasing soil quality, the biochar amendments sequester carbon within the soil.

Abstract:

On the semiarid Colorado Plateau, dryland farmers are challenged by degraded soils and unreliable precipitation. While cover crops have been shown to support soil fertility, control erosion, and enhance in soil water capture, they also use limited soil water and, thus, may impact cash crop productivity in dryland systems. Most literature on cover crops comes from relatively humid climates, where yield penalties due to cover crops may be less pronounced. Two field trials were conducted in Southwestern Colorado to assess the short-term viability of cover crops in dryland systems in this region.

Abstract:

Among the problems of physical degradation, compaction and densification are the main ones, and they cause strong decreases in subsequent crop yields thereof. The degradation of soil structure is a worldwide problem that can occur in all soils and livestock production levels. Given the above, this paper aims to analyze the main changes in the internal structure of the soil as a result of compaction by trampling of animals. Soil compaction due to the collapse or decrease in pore spaces, is the most common cause of physical restraint to growth and root development. As an aggravating factor, degr

AbstractSoil erosion is occurring at an alarming rate and threatens soil productivity and crop growth. A regional research committee was formed in the North Central region of the US in 1983 to develop a better understanding of soil erosion and productivity relationships on a broad geographic scale. This paper presents the history, project development and implementation and results of the committee, and a perspective on soil erosion-productivity research approaches.

Soil acidity is a major problem when it comes to improving crop productivity and nutrient uptake. This experiment was therefore conducted at a farmer’s field—Nalitabari Upazila under AEZ 22 (northern and eastern Piedmont plains) to evaluate the effects of lime and organic manure (OM) amendment on crop productivity and nutrient uptake of the wheat–mungbean–T.

Abstract:

The productivity of irrigated agriculture in Australia is low for most crops and one important factor is the physical and chemical constraints caused by sodicity in the rootzone. Over 80% of the irrigated soils are sodic and have degraded structure limiting water and gas transport and root growth. Irrigation, without appropriate drainage, leads to the buildup of salts in soil solutions with increased sodium adsorption ratio (SAR) and can develop perched watertables due to a very low leaching fraction of the soil layers exacerbated by sodicity. Therefore, irrigation management in Australia is c

Disinfecting soil can reduce or eliminate crop loss from soilborne pathogens, parasitic nematodes, and weed competition. Biosolarization combines biotoxic products from organic matter decomposition and heat from solarization. While biosolarization offers an organic option for soil pest control and avoids human and environmental health risks associated with chemical fumigants, it still has broad negative impacts on microbial communities. Quickly reestablishing these communities can be key in preventing resurgence in disease pressure and in maximizing nutrient use efficiency. The objective of th

Soil organic matter (SOM) in agricultural soils is generally lower in cultivated and intensively managed cropping soils than in pasture soils. Cultivation during the transition from pasture to crop leads to a loss of SOM, which may affect soil functionality and subsequent agricultural productivity. However, it is unclear how management practices influence SOM dynamics following this transition. We investigated the impact of initial soil fertility and application of lime and nutrients (nitrogen (N), phosphorus (P) and sulfur (S)) on changes in soil carbon (C) during the transition from a perman

SUMMARYThe area of salt-affected land is increasing because of irrigation practices and changed land use. Breeding crops that tolerate soil salinity and yield well in salt-affected soils, and employing crop management practices to counter salinity, have been proposed to maintain crop productivity. Here, it is argued that neither breeding nor management will adequately counter the effects of salinity. Although both offer the potential to maintain yields for a brief period, it is inevitable that salinity will continue to increase and crop productivity will decline. Only the establishment of a pe
