Effects of legume cover crop and sub-soiling on soil properties and Maize (Zea mays L) growth in semi arid area of Machakos district, Kenya = Efecto del cultivo de cobertua y el subsolado sobre las propiedades del suelo y crecimiento de maiz (Zea mays L.) en la region semi arida de Machakos, Kenia [PDF]

Low crop yields in the semi arid areas of Kenya have been attributed to, among other factors, low soil fertility, low farm inputs, labour constraints and inappropriate tillage practices that lead to pulverized soils.

Planting Techniques for Establishing Loblolly Pine Seedlings on Two Subsoiled Sites in Arkansas [PDF]

, 2007
The presence of soil compaction and root-restricting layers (e.g., plow pans) resulting from long-term agricultural practices often poses difficulties when converting these sites into loblolly pine plantations.

Depth‐dependent mechanisms regulate accumulation of plant‐ and microbial‐derived residues under long‐term nitrogen addition in a semiarid grassland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...

Development of a Mathematical Model and Structural Optimization of the Specific Resistance of a Broken Line Subsoiler

Agriculture
Saline-alkali soil has the characteristics of high density, high firmness and poor permeability. Aiming at the problems of shallow subsoiling depth, large subsoiling specific resistance and small soil bulkiness in subsoiling operation in saline-alkali ...

Tilling tests of rotary tiller and power harrow after subsoiling

, 2020
Soil preparation is one of the most energy-consuming activities in plant production. To reduce the operating cost and the soil compaction effect, researchers have tried to decrease the number of machinery passes required for soil preparation, including ...

Long‐term warming drives mineral‐associated organic carbon accumulation on the Tibetan Plateau

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global warming affects both plant growth and soil microbial decomposition, creating uncertainty for the storage and persistence of soil organic carbon (SOC) stock. Limited decomposition rates often characterise cold alpine ecosystems.

Research Progress on the Physiological Mechanisms and Regulatory Effects of Subsoiling Depth on Spring Maize Yield Formation

Guangdong nongye kexue
As one of the world's three major grain crops, maize is a key crop for ensuring food security. However, problems such as compacted plow pan, insufficient soil water retention capacity, and relatively low resource use efficiency severely limit the yield ...

Addressing Soil Degradation in EU Agriculture: Relevant Processes, Practices and Policies - Report on the project 'Sustainable Agriculture and Soil Conservation (SoCo)' [PDF]

, 2009
Agriculture occupies a substantial proportion of the European land, and consequently plays an important role in maintaining natural resources and cultural landscapes, a precondition for other human activities in rural areas.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Restoration of Soil Health for Achieving Sustainable Growth in Agriculture [PDF]

Total geographical area of Pakistan is 79.61 million hectares (m.ha.). Area under cultivation is 21.59 m.ha.; of which, only 5.34 m.ha. (i.e., 25 percent) is free from soil limitations and is fit for intensive agriculture [Mian and Mirza (1993)].
