Importance of potash for crop production
All plants take their food in the form of nutrients. Be it food crops, vegetable crops or fruit trees, postash is an essential nutrient for everyone. If the nutrients consumed by almost all the crops are not compensated by fertilizers and manure, there is a special deficiency of the element in the soil and the plant starts dying.

Therefore crops need to be given these important elements. All plants require at least 16 elements for growth and development. Of these, carbon (C). Hydrogen (H) and oxygen (O) are obtained from water and air.
The other 13 elements come from soil, fertilizers and manures. Use of Potash In the crop from flowering to fruiting, it is considered appropriate to use potash between 35-70 days of harvest because it is during this time that the plant requires maximum potash.
Different crops absorb certain but different amounts of nutrients. This depends on the nature of the crop. Due to lack of any nutrients in the soil, proper growth of plants is not possible.
Therefore, the use of manure and fertilizer should be balanced in such a way that the crop can get all the necessary nutrients in sufficient but proper quantity. This type of systematic fertilizer application is called balanced fertilizer application.
Chemical fertilizer and its impact on Agriculture.
Potash is an essential nutrient. Potash is essential for the growth and development of plants. Potash helps to protect the crops from adverse weather conditions like drought, hail, frost and insect-disease etc.
Potash prevents rotting of crops by allowing proper root growth. Due to the use of potash, the cell walls of plants are thickened and the stem grows in layers of cells. As a result of which the crop is protected from falling.
Crops that get the full amount of potassium require relatively little water to produce the desired yield. In this way the use of potassium improves the water-use efficiency of the crop.
Potash is the most important factor in improving the quality of crops. Potash enhances the yield properties by increasing the color, aroma, sweetness, strength and weight of the product.

Due to the necessary supply of potassium to the crops, there is a significant increase in the capacity of nutrients like phosphorus and zinc.
Symptoms of potassium deficiency in plants
1. Decreased growth and development of plants.
2. Darkening of leaves
3. Yellowing of the tips or margins of older leaves.
4. Subsequent tissue dying and drying of the leaves
If once the signs of deficiency of a particular element are seen in the crop then you understand that the crop has been damaged which is not completely treated, in such a situation the use of potash will not give full benefit.
In case of latent potash deficiency in plants, we see that healthy plants give relatively high yields with the use of potash. So if you wait until the crop shows signs of potash deficiency, it will be too late and you will not be able to protect the crop.
What is the future of Agriculture & Farming?
It is said that potash is abundant in the soils of but this is not true. Due to high yielding varieties of crops and adoption of new and advanced techniques of agriculture there has been a shortage of potash in the land.
Since the supply of potash could not be achieved in the ratio in which there was more production and more removal of potash. Therefore, now the lack of potash in the soils is becoming apparent.
Application of potash should be done with nitrogen and phosphorous fertilizers. Potash enhances the effect of nitrogen and phosphorus in plant nutrition. Thus the use of potash gives maximum yield highest product quality and maximum profit.
Application and use of Biotechnology in Agriculture.
Potash fertilizer is usually available in the form of potassium chloride. It is cleaned from the mine and is available in the market in the form of pure salt fertilizer as Murate of Potash.
Apart from this, potash is also supplied from potassium sulphate and sulpomag. Generally potash manure should be used at the time of sowing or transplanting, but in light ie sandy soil, potash can be used divided. To gain weight you also need to provide Potash befor the harvesting of vegetable crops.
Farmers can purchase Potash from their nearest fertilizer vendor. These vendors are across the public, private and cooperative where you can by them in the form of chemicals.
How to do solar power fencing for crop protection?
You must purchase good quality potash fertilizer from Agriculture department authorized or licensed vendor in India. For use in Drip Irrigation System you can use white potash just beacuse it is soluble in water. Red potash is insloluble in water so you should avoid this for use in ventury with Drip System.
Conclusion:
Potash should be used in conjunction with nitrogen and phosphorous fertilizers. Potash enhances the effect of nitrogen and phosphorus in plant nutrition. Thus the use of potash gives maximum yield, highest product quality and maximum profit. Potash is commonly found in the form of potassium chloride. If once the signs of deficiency of a particular element are seen in the crop then you can which is not completely treated. In such a situation, the use of potash will not give full benefit.
In case of latent potash deficiency in plants, we see that healthy plants give relatively high yields with the use of potash. Therefore, if you wait until the symptoms of potash deficiency appear in the crop, it will be too late and you will not be able to protect the crop.
