In order to analyze the effect of different tillage methods on the amounts of treflan herbicide controlling weed in experimental seeding canola farms a test in the form of the factorial experiment was done as Randomized complete Block design in 4 frequencies and 9 treatments in DEZFUL Agriculture and industry Martyr Beheshti in farming year 2007-2008. Results of the test showed that ratings of herbicide treflan on sevevel weed of Berseem- clover has been meaningful at a level of 5 percent and hasn't
Introduction Soil carbon sequestration (SCS) is the removal of atmospheric Co2 and its long-term storage in soils as soil organic carbon, soil organic matter (decomposing plant and animal tissues) and soil inorganic carbon. Carbon is sequestered in oceans, geological landforms, vegetation and soils; about 75% of the carbon sequestered on land is stored in soils (Powlson et al, 2011). The size of the flow of CO2 to and fro the atmosphere into oceans, soil and geologic landforms will determine if
In addition to these challenges, the principal indicators of non-sustainability of agricultural systems include; soil erosion, soil organic matter decline, and salinization. These are caused mainly by: (i) intensive tillage induced soil organic matter decline, soil structural degradation, water and wind erosion, reduced water infiltration rates, surface sealing and crusting, and soil compaction; (ii) insufficient return of organic material (Bhan and Behera, 2014). Therefore, a paradigm shift in
Study Questions: 1.) Why is sub-soiling needed in soils with hard pans? Sub-soiling is essential especially to hard pan layer because it will help the roots penetrate deep and be able to explore and obtain water and nutrients from larger volume of soil. Hard span obstructs root's downward proliferation and restricts root growth of crops (of crops that have vertical root growth). With sub-soiling, the needed soil depth, at least 80cm will be met . With sub-soiling, we can break hard pan without
Soil, which is one of the most important natural resources, is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us, human beings, taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved, a part of the natural wealth that needs to be preserved.
What is soil erosion? Soil erosion is a natural process, occurring over geological time, and indeed it is a process that is essential for soil formation in the first place. With respect to soil degradation, most concerns about erosion are related to accelerated erosion, where the natural rate has been significantly increased mostly by human activity. Soil erosion by water is a widespread problem throughout Europe. Soil is naturally removed by the action of water or wind: such 'background'
INTRODUCTION Soil is the precious gift of nature to the mankind. All the plant family, animal kingdom and human society at large depend upon soil for their sustenance directly or indirectly. Ironically, soil is the most neglected commodity on the earth. Shifting cultivation on the hill slopes, non-adoption of soil conservation techniques, and over exploitation of land for crop production due to population stress, leads to enormous soil erosion. It will take hundreds of years to form an inch of soil, but

the structure of soil and plant formation. Microorganisms, which include many different fungi, bacteria, and actinomycetes, are considered the architects of the soil as they have the ability to create a strong ecosystem in the soil. Microorganisms work best in communities to develop the structures for plants. For microorganisms to thrive there has to be a diverse amount of nutrients in the soil for them to feed off of. Schulz (2013) explains, “soil aggregation is of upmost importance in controlling
