The farm’s plastic consumption is increasing. The use of plastic for agriculture is called plastic culture. There is a process of covering the soil to save water, weeds, labor, disease. In which a large amount of plastic is being used. Out of 90 lakh hectares of land in Gujarat, plastic or agricultural waste is disposed on 10% of the land in summer and winter crops.
40 percent increase in production
According to the study of Navsari Agricultural University, plastic mulching, the agricultural scientist Mukesh Jinjala said that 90 percent weed is not there. Saves 40 percent of water. In summer or winter there is 60 percent water left in chillies. 20 percent fertilizer is left. Thus about 40 percent of the total cost of cultivation is saved from mulching. Therefore, farmers are increasingly increasing plastic mulching.
Two to three times the crop
Cotton and groundnut give twofold yield. Watermelon cultivation in Gujarat is mostly done by plastic mulching. In Gujarat, it is being used in lakhs of hectares apart from monsoon in watermelon, chillies, tomatoes, cucumber, vine and vegetables.
Water saving 40 percent
The plastic cover allows moisture to remain inside the soil for a long time. Less water can be used to grow crops in more area. Money can be saved by stopping the water from evaporating. Where the plastic is laid, the steam settles under it and falls back into the ground. So the waste of water stops.
Saves up to 90 percent on weeding costs.
Photosynthesis stops inside the gel. Roots or weeds do not grow in the soil. Therefore 40 to 90 percent weeding is not required.
The ground is not hot
Sunlight does not fall directly on the ground. Mulberry is a good advantage in arid and semi-arid areas. A lot of money is left for those who buy water. The sunlight on the plastic makes the soil less hot. Since there is air in the space between the plastic and the ground, it becomes a heat insulator. It also helps in the cold. Night and day temperatures also help.
Removing toxins purifies the soil – viruses, bacteria, harmful substances that damage the soil. Made of insect free soil. Water, phosphorus, micronutrients are saved by increasing carbon dioxide. So the crop is good. Therefore production comes more. Also, the elements that are destroyed by sunlight are not. No change in soil has been observed.
Hole in the ground
Empty soil flies low from the ground. Holes in the ground are maintained. Hence the circulation of air is more. Which helps in photosynthesis.
Black and white comes shiny plastic. It also has immense viewership and transparency. Linear Low Density Polyethylene – L. LDPE. The type is most commonly used on farms. In which the holes do not fall soon. They are thin and strong. Weeds do not come out.
Polyvinyl chloride – PVC and low density polyethylene – L. DPE. Plastic also comes.
The plaster of dust has to be broken before plastering. Planting should be done before planting or sowing. Plants make round holes to plant or exit, squares tear off the plastic. Press 2 to 6 inches deep into the ground or press 6 inches of soil.
For this purpose, first dried leaves, husk, stalks, sawdust, banana leaves, sugarcane leaves, paddy husk, dried pastry or corn husk are covered on the ground. So the moisture evaporates less. Machine cutters can be cut into small pieces and placed on the ground. The field is cultivated with compost and mulching.
The price of 20 micron black plastic is between Rs 2200 to Rs 2300. Which is 2 to 2.50 feet wide. The length is 800 meters. Which should roll 4 to 5 in 3 acres of land (acres)
25 micron black plastic comes in the range of Rs 2500 to Rs 2600. The cost of 20 micron plastic is 20 to 25 thousand rupees per hectare. This means that it costs between Rs 2 to Rs 2.50 per square meter.
7 microns for peanuts, 15 to 25 microns for eggplants, tomatoes, okra, cucumber, cabbage, vegetables, vines, 50 microns for papaya, fruits, flowers are used for plastics. 100 micron plastic is used for tree crops like mango, coconut, chiku, guava. Crops like wheat and cumin are not grown. (Translated from Gujarati)
