Within a year, there should be rotation between plants that are not able to produce a lot of green materials such as soybeans and green beans with plants that can produce a lot of material Iebih seperli forage maize and sorghum. Kenyatan shows that in densely populated areas like watersheds in Java, the attempt to restore the land to waste is very difficult to do. This is caused by the use of waste for various other purposes such as for livestock, industry, firewood and so on.
Consequently the levels of soil organic matter is difficult and productivity is maintained mostly dry land becomes very low. In conservation farming combined with livestock, most often used for livestock waste. When all the manure can be returned to the soil, the soil organic matter content can be maintained. One way to maintain land productivity is the effort to produce forage material in bulk and return it to the soil as a mulch (distributed on the surface) or buried in the soil tillage time.
When the dry season arrives … when its farmers to make crop rotation. Start by planting corn, soy beans planted long … ..ada also conducting pattern of rice, corn and tobacco.
Crop rotation in order to enable farmers to remain productive farming even though the water supply, air less … so do besides rice planting as the example mentioned above …. It also can begin planting cucumbers, melons, peanuts, chili and onions and many more depending on the circumstances of each region.
Outside the problem of water crisis anticipation, crop rotation actually have important functions is to break the cycle of proliferation of pests and plant diseases in addition to suppress the occurrence of erosion and prevent depletion of nutrients from the soil. Crop rotation is necessary also to maintain and improve the physical properties and soil fertility. This occurs when the crop residues into compost or mulch embedded in the soil. This will enhance the ability of soil to withstand and absorb water, enhances the stability and absorption capacity of the soil.
If the plants are dipergilirkan is a legume plants (legumes) will increase the nitrogen content (N) of land that is very beneficial for vegetative growth of the plants. Also will maintain nutrient balance for their absorption elements from different depths. Well … if you see the usefulness of this all … then crop rotation is highly recommended … that the peasants remain productive and continue to reap the rewards grow despite the dry season cropping. Add the dry season as an opportunity not a threat ….
