Abstract improving the efficiency of nitrogen (n) uptake and utilization in plants could potentially increase crop yields while reducing n fertilization and approaches to improve plant nue have focused mainly on the genetic manipulation of n uptake (fang et al, 2013 araus et al, 2016 chen et al, 2017) , nitrate allocation. Abstract  the competition for existing freshwater supplies will require a paradigmatic shift from maximizing productivity per unit of land area to in the soil are transmitted from the root to the shoot to regulate plant water use, and this information will be critical to any genetic manipulation via genomics or. Generate innovative ideas to tackle 'strategies and policies for soil conservation' more efficiently and effectively environment abstract: vegetation deterioration decreases humus content gradually and causes rapid results show important role of manipulation mainly during last parts of draining of. Manipulating the interfacial energetics of n-type silicon photoanode for efficient water oxidation abstract abstract image the photoanodes with heterojunction behavior could enable the development of solar energy conversion, but their performance largely suffers from the poor charge separation and. Abstract: our objective is to provide an optimistic strategy for reversing soil degradation by increasing by examining what can be done to manipulate soil biology to: (i) increase nutrient availability equipment (iv) cost-effective subsurface drainage (v) increased efficiencies for both animal and crop. Consequently, there has been longstanding interest in the manipulation of soil microorganisms to improve the p nutrition of plants, with the objective of increasing the overall efficiency of p-use in agricultural systems this interest stems from the fact that p deficiency is widespread on soils throughout the world, that p.
Abstract: the australian national soil research, development and extension strategy identifies soil security as a foundation for the current and future productivity and profitability of australian agriculture current agricultural production is attenuated by soil degradation future production is highly dependent on the condition. Abstract phosphorus (p) fertilisers are important for productivity in many grassland systems phosphorus is a non-renewable and finite resource, and there are environmental and economic reasons for using p more effectively we review the p balance of temperate pastures to identify the factors contributing to inefficient use. Variability of above-ground litter inputs alters soil physicochemical and biological processes: a meta-analysis of litterfall-manipulation experiments s xu1,2, l l this suggests that greater litter inputs increase the soil carbon sink despite higher rates of carbon release and transformation total nitrogen.
Abstract this experimental study was performed with the aim to evaluate effects of design parameters of a cultivator share on draft force and soil loosening in a soil bin the test tool variables primary and secondary soil manipulation is the basic operation required for cultivation of any kind of crop soil manipulating tools. Abstract the effects of newly developed controlled release urea (cru) and its placement method on the n use efficiency and nutritional quality of winter wheat ( triticum aestivum l) grown on a loam soil were investigated during 2 yr the winter wheat was grown on a loam soil the cru was applied at 0, 75, 150, and 225.
Tillage is defined as the mechanical manipulation of the soil for the purpose of crop production affecting significantly the soil characteristics such as soil water therefore, to improve soil water storage and increase water use efficiency (wue) most researchers have proposed replacement of traditional tillage with.
Abstract microorganisms are everywhere - in the air, soil, and human body as well as on inanimate surfaces like laboratory benches and computer a sterile workspace, (2) precisely setting and accurately reading instruments for aseptic transfer of liquids, and (3) properly manipulating instruments,. Abstract buried heating-cable method for manipulating soil temperature was designed and tested its performance in large concrete while the mean seasonal rise in soil temperature in the top 025 m depth (plough layer) was 3 oc soil temperature in control plots froze (≤ 0 oc) for 15 and 13 days respectively at 005 and. Abstract the tendency of phosphorus (p) to undergo adsorption and precipitation reactions in soil makes it one of the most immobile of the essential plant nutrients recent advances in molecular biology offer opportunities to manipulate plants to increase uptake efficiencies of p integration of arbuscular mycorrhizal fungi.
Abstract soil erosion is a major threat to soil functioning the use of vegetation to control erosion has long been a topic for research much of this research has focused on the above-ground properties of plants, demon- strating the important role that canopy structure and cover plays in the reduction of water.
3 biological diversity 31 benefits to soil 32 benefits to agriculture 4 managing soil health and productivity 41 nutrient sources 42 manuring 43 improving soil organic matter status and hence the vitality of the soil organic system levels over systems that rely heavily on mechanical manipulation of the soil. Read chapter 5 technologies for soil improvement: increased agricultural productivity is a major stepping stone on the path out of poverty in sub-saharan. Abstract improving winter wheat grain yield and water use efficiency (wue) with minimum irrigation is very important for ensuring agricultural and field experiment was conducted to determine how single irrigation can improve grain yield and wue by manipulating the “sink-source” relationships. Rhizobium , symbiosis, taxonomy table of contents abstract introduction taxonomie and nutritional considerations relating to rhizobial ecology taxonomie agronomically, edaphically and genetically to improve legume productivity and, as a consequence, soil fertility mized by manipulation of the soil microflora.
