Weeds also degrade quality of the produce, raise cost of production; harbor and serve as alternate hosts to several insect pests and diseases. The inorganic metal composition of soil depends on both natural and anthropogenic factors. Soil Tillage Res., 17: 115-124. Conservation tillage systems showed higher net returns versus conventional tillage and reduced farmer operating costs. Main objectives of conservation agriculture is reducing tillage, year round cropping, crop rotation, mulching may be live or residue. Overall, reduced tillage was found to be the most suitable tillage option under rice based diversified cropping systems. The results of this study evinced that reduced tillage is suitable in this region, since it is promising in the SOM enhancement. The olive yield responses to each production system were evaluated, and the selected physico-chemical soil properties (pH, bulk density, soil organic carbon, cation exchange capacity, total N, P, and K), soil enzymes (β-glucosidase, protease, dehydrogenase, and phosphatase activities), and soil-microbial biomass C and N were monitored. The effects of two tillage systems and three crop rotations on the aggregation indices were studied. The implementation of sustainable soil management strategies is vital for hillslopes and low-fertility soils where plantations cover vast tracts of land. The improved grain output of wheat was primarily due to increased tiller development in CT treatments during both the years. 34 0 obj

The results obtained from various studies showed that the no-till treatment caused lower infiltration rates ( Abu-Hamdeh, 2002;Lipiec et al., 2006;Matula, 2003). It was more noticeable in no-tillage corn than in conventionally tilled corn. By Maureen Kuwano Hinkle. Moreover, a crop rotation allowing sustainable and continuous production can be created. Soc.Am.Proc. (1993). and Develop, IV :1-23, Clements, R.D., et al. Numerous studies … However, some researchers indicated that the no-till treatment can increase infiltration due to higher surface residue and macropore connectivity between the top and bottom soil layers ( Strudley et al., 2008; ... At the same time, the no-till practice could reduce the loss of soil moisture to the atmosphere through evaporation. (2002). We suggest that at this stage soil tillage research in the semi-arid regions of Africa and Asia should re-examine some of the concepts of conservation tillage in relation to soil physical properties and processes in order to obtain a tillage system that ensures high crop yields without destruction of the soil resource. It reduces greenhouse gas emission and also it can improve carbon sequestration. The NT practice manifested the best results with 3.5-fold fuel saving and 2.2-fold human labor saving as well as 7.8 times more operating area per unit time compared with CT. Notwithstanding, it seems that since most of the SAT soils are structurally unstable, further conventional tillage even though it has ephemeral advantages, may in the long term be exacerbating the problems of structural instability and their deleterious effect on water and soil conservation and therefore on crop production. Adv.Agron. Rabat, Morroco. Continuous rice–wheat cropping system with intensive conventional tillage operations have been showing natural resource degradation. Weed Sci., 42 : 205-209, Burford, J.R., et al. Because several researchers expressed that notill treatment provides more surface cover and so lower evaporation (Lampurlanés and Cantero-Martínez, 2006; ... Higher infiltration rates at T2 and T4 could be explained with strong surface aggregates and continuity of macropores along the soil depth. CA and weed management are discussed in detail elsewhere. Diverse climatic conditions in India favor the most adopted weeds to prevail and cause severe crop yield losses. Soil samples were collected from disturbed and undisturbed plots of NT as well as plots under other tillage systems from three soil depths (i.e., 0-10, 10-20 and 20-30 cm) in November 2016. Conservation tillage decreases soil erosion, leaching of fertilizer, pesticides and herbicides into the ground water. Precise definitions of conservation tillage are only possible within the context of known crop species, soil types and conditions, and climates. Agron. 0000001009 00000 n
