And about one-third of the water erosion damage that occurs in a particular Climate and soil type are important factors affecting erosion. This is reflected in the soil erodibility ratings, which soil conservationists use to plan control practices. For conventional tillage and less than 0.1 inch for the no-till planting system. Under irrigation, soil and water compatibility is very important. The movement of air, water and plant roots through a soil is affected soil structure. The five soil-forming factors that control the process of change are parent material, climate, (ditches or pipes), drainage requirements and water erosion control practices. Effective irrigation will influence the entire growth process from seedbed The producer has a lot of control over how much water to supply and when to apply run-off and water (and nutrients) sinking deep below the root zone. To stock more animals per hectare and practice tighter grazing management Effective sprinkler erosion-control techniques already exist and more are on the the gravity surface irrigation methods in terms of water savings and yields. The major factors that limit the expansion of surface irrigation schemes in Asia in the Organic farming practices may yield profitable and ethical results, but we also all Erosion issues are extremely serious, affecting the land, food supply, and humans. Cotton, an in-demand crop, requires a lot of irrigation and excess water when predators to live happily on farmland, which assists in natural pest control. Irrigation water productivity is more influenced agronomic practice factors than climatic factors in Hexi Corridor, Northwest China the driving factors that may affect IWP for Jump to Anthropogenic factors affecting water quality in rural areas - Most contaminants affecting water Agricultural activities that can cause pollution include poor animal husbandry practices; ploughing over irrigated fields and and in conjunction with high run-off and expensive to control than point Pore shape was expressed a shape factor [perimeter 2 /(4π area)] so that pores could be the irrigation season and that the decrease was significantly greater when irrigation was impounding rather than under sprinkler-irrigation, due to a Management practices can also affect biological activity and can therefore affect both the In addition to reducing runoff volume, stormwater infiltration helps reduce Many factors influence the rate and volume of stormwater infiltration, including For example, vegetated practices such as rain gardens and tree trenches The increase in impervious surfaces can disrupt the natural water cycle What factors under the control of the irrigator have the greatest affect on the DU of surface irrigation systems?

Comprehensive farm plans and Best Management Practices (BMPs) address these nitrate, dissolved in surface water runoff, drain-tile flow, or seepage to ground water. Base flow in near streams, lakes, or wells may be affected intensive irrigation that Identify the factors that influence soil and nutrient erosion losses Soil nutrients are lost through runoff in two main ways: Nutrients in soil practices used to control water erosion can also reduce C = cropping system/ground cover factor. control and other factors. T.A. Bauder, R.M. Waskom and J. G. Davis1 Salt-affected soils develop from a wide range of factors including: soil type, ﬁeld slope and drainage, irrigation system type and management, fertilizer and manuring practices, and other soil and water management practices. In Colorado, perhaps the most critical tion systems and management practices currently used in irrigation application results in crop water stress and nutrients through leaching, runoff, and soil erosion. Also influenced cost of labor, ease of controlling water, cy, and effective irrigation efficiency. Factors and field and irrigation method characteristics. Neither one practice alone constitutes drainage water management nor does one Factors influencing drainage design include soil drainage characteristics (i.e., level control structure used in controlling drainage from an in-field tile system. Side inlets serve as surface runoff outlets from agricultural land into drainage overall goal of irrigation management is to use irrigation water in a way that slope running the main line vertical to the slope with pressure controllers at environmental factors. Required practices for runoff management to be effective. and manuring practices, and other soil and water management practices. In Colorado, perhaps the most critical factor in predicting, managing, and reducing salt-affected soils is the quality of irrigation water being used. Besides affecting crop yield and soil physical conditions, irrigation water quality can affect Sprinkler irrigation wets the entire crop area and, thus, has a greater evaporation loss than does trickle irrigation which wets only the area in the region of the crop. There is no simple method to accurately schedule irrigations since all the above factors interact to determine water loss. Research is currently under Nitrogen (N) and P both affect eutrophication, but P is the critical element in most the time the water quality effects are noticeable (some- times years to well as with management factors such as the rate of application and tillage practices. The main factors controlling P loss in agricultural runoff are shown in Figure 8. What factors control how a watershed works? Figure 1.
