Detailed Explanation of Watermelon's Fertilizer Requirements and Key Fertilization Points

(Agricultural Wealth Network) The watermelon plant has a relatively short whole growth period, and its fruit is very large, so the plant has a considerable demand for fertilizer throughout its life, and its demand ratio for nitrogen, phosphorus and potassium also differs, with potassium being the highest, phosphorus the lowest, and nitrogen in the middle. Calculating at 1000 watermelon plants planted per mu, a total of 14.5 kg of nitrogen, 4.8 kg of phosphorus dioxide and 20.4 kg of potassium oxide can be absorbed. The absorption ratio of nitrogen, phosphorus and potassium is 3 to 1 to 4.
