Abstract Abandoned agricultural lands often accumulate soil carbon (C) following depletion of C by cultivation. The potential for this recovery to provide significant storage benefits depends on the rate accumulation, which, in turn, may depend nutrient supply rates. We tracked almost four decades intensive disturbance along an experimentally imposed gradient nitrogen (N) added annually combina...

knowledge of physiological and environmental factors is important for foragegrass production. festuca ovina is a grass species adapted to azerbaijan region climate,iran. this species is a valuable source for forage production and soil conservation.nitrogen (n), phosphorus (p) and potassium (k) are three most important plant nutrients.the aims of present study were to investigate the effects of ...

The System of Rice Intensification (SRI) follows a set of principles in rice production management for a more efficient interaction between plants, soil, water and nutrients; creating a congenial environment for the healthy growth of plants and realizing their best potential productive capacity. In brief, SRI involves: • Carefully planting single, young seedlings at optimally wide spacing • Kee...

Plants may induce small-scale heterogeneity in soil nutrients, forming fertile islands. However, this process may depend on plant spices, plant developmental stages and habitat conditions. Vegetation cover in arid and semi-arid regions is mostly in the form of plant patches and bare soil of inter-patch areas, this form of vegetation cover can be useful to study plants impact on soil to get appl...

Plant nutrients are essential for the production of crops and healthy food for the world’s expanding population. Plant nutrients are therefore a vital component of sustainable agriculture. Increased crop production largely relies on the type of fertilizers used to supplement essential nutrients for plants. The nature and the characteristics of nutrient release of chemical, organic and biofertil...

To understand the responses to external disturbance such as defoliation and possible feedback mechanisms at global change in terrestrial ecosystems, it is necessary to examine the extent and nature of effects on aboveground-belowground interactions. We studied a temperate heathland system subjected to experimental climate and atmospheric factors based on prognoses for year 2075 and further expo...

Plants have need for about 18 essential nutrients. Of these essential nutrients, several are classified as trace metals, namely: zinc, iron, manganese, copper, boron, molybdenum, cobalt, and nickel. In addition, other trace metals commonly exist in soil that can be taken up, such as arsenic, chromium, iodine, selenium, and others. Some of these elements are more or less inert in the plant and o...

flood water contains high amount of sediment affecting the fertility of the coarse grain alluvial fans and flood plains through increasing nutrients. in this study, the effects of the flood water spreading on the soil nutrients recovery were investigated during 10 years (2004-2014) at the poldasht flood spreading station of west azarbaijan in iran. flooded three upper strips were selected at th...

Most dairy farms in Wisconsin continue to produce most of their feed and have sufficient land for recycling manure nutrients through crops. However, to remain economically viable, many dairy farms are increasing herd size and importing more feed. The increased importation of nutrients in the form of feed and fertilizer has resulted in excessive soil nutrient accumulation (Bundy, 1998; Proost, 1...

Replenishing nutrients through organic sources is essential to maintain the soil health and sustainability in Eastern Himalayan Region, India which is organic by default. Keeping this in mind an experiment was laid out on randomized block design with six treatments viz., T1: Vermicompost (VC; 2.5 Mg ha-1), T2: Poultry manure (PM; 1.25 Mg ha-1), T3: Swine manure (SM; 3.0 Mg ha-1), T4: Cow du...
