SOIL TILLAGE is a farming practice that helps to prepare the soil for plant growth. It can be done with a tractor, an implement called a or a tool called a Tillage has long been used for seedbed preparation, weed suppression, soil aeration, cover crops and forages, burying crop residue, levelling the soil, incorporating manure and fertiliser into the root zone and activating pesticides. Tillage harrow, disc plough. turning over Tillage systems is a method found worldwide which prepares a farm seedbed free of by ploughing, disking once or twice to break the soil clods, and collecting the plant residues. Conventional tillage clods involves no seedbed preparation other than opening the soil to place the seed. Zero tillage limits tillage operations to those essential to crop production and prevention of soil damage, often executed with specific machines (e.g. harrow) only once a year. Minimum tillage leaves a high quantity of plant residues (at least 30%) on the soil surface for erosion control and moisture conservation, normally by not inverting the soil. Conservation tillage 1 MORE This practice benefits farmers by reducing fuel consumption, labour requirements and fertiliser cost. 1 Impact on soil quality There are many characteristics and indicators of soil quality, including good soil pores and water-holding capacity, good infiltration rates, and overall high levels of organic matter and beneficial soil organisms. Unfortunately, tillage can negatively impact almost all of soil characteristics. Moreover, intensive soil tillage can increase the probability of soil erosion, nutrient into nearby waterways, and the release of greenhouse gases into the atmosphere. A reduction in how often or how intensively cropland is enables the soil to retain more organic matter, which leaves the soil less susceptible to wind and water erosion and helps store, or “sequester”, carbon. Also, tillage has always been contributing negatively to soil quality. Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which helps the force of raindrops. Luckily, modern agriculture has greatly reduced the use of soil tillage; however, the most effective soil conservation system is zero tillage farming, in which the soil is left undisturbed by tillage and residue is left on the soil surface. tilth, runoff tilled cushion pounding
