Que Phong replicates the deep fertilization model
(Baonghean) - After a year of using deep-planted fertilizer, the ethnic people of Que Phong district have seen much higher rice yields than when using broadcast fertilizer before. This spring crop, the district has a policy of continuing to support the expansion of the model...
Mr. Trinh Xuan Dung, Head of the District Agriculture Department, said: Comparing the effectiveness of deep-rooted fertilization with broadcast fertilization in the spring crop last year, it shows that 1 hectare of rice, if fertilized with deep-rooted fertilization, will require 250 kg multiplied by the price of 13.5 thousand VND/kg = 3,375 VND; broadcast fertilization requires 500 kg of NPK multiplied by the price of 6.2 thousand VND/kg = 3,100 VND. However, the yield of the area fertilized with deep-rooted fertilization is on average 57 quintals/ha, while the average yield of broadcast fertilization is 43 quintals/ha. Thus, the investment in deep-rooted fertilization is slightly higher than broadcast fertilization, but the yield of deep-rooted fertilization is much higher than broadcast fertilization. Obviously, using deep-rooted fertilization is more economically efficient, and more importantly, using deep-rooted fertilization prevents soil erosion, which is very suitable for rice production on terraced fields.
Spring rice fields in Chau Kim commune that apply deep fertilizer all grow well.
Realizing the effectiveness, this year Que Phong continues to use the capital of the Government's Program 30a, 102 to support farmers to invest in buying bamboo rat fertilizer for 1,000 hectares of spring rice (last spring crop Que Phong used bamboo rat fertilizer for 570 hectares). To promptly supply enough bamboo rat fertilizer for farmers, Que Phong district assigned 2 specialized agricultural service cooperatives to produce, Quang Truong Cooperative, Tien Phong commune and Chau Kim Cooperative.
Mr. Ha Van Hoa, a farmer in Do village, Chau Kim commune, boasted: His family has 3 sao of rice fields, last year he applied 2 sao of rice straw fertilizer, and saw that the rice yield was much higher than previous years. This spring, his family applied 3 sao of rice straw fertilizer, and so far the rice plants have grown well. According to our observations in the fields of Do village, the rice fields fertilized with mulch fertilizer grow much better than those fertilized with broadcast fertilizer. And the rice fields fertilized with mulch fertilizer use the method of planting in wide and narrow rows to facilitate fertilization.
Ms. Vi Thi Thuy, Chairwoman of Chau Kim Commune People's Committee, said: This spring crop, the locality planted 197.3 hectares of rice. The characteristic of the cultivated land here is terraced fields, so applying dung fertilizer is very effective. Therefore, this spring crop, farmers in the commune applied dung fertilizer on an area of 70 hectares (last spring crop applied dung fertilizer on 65 hectares). This spring crop, farmers should have applied dung fertilizer on a much higher area than the previous crop, but because the amount of dung fertilizer produced by Chau Kim Agricultural Cooperative had to supply models in other communes, it was not enough to meet demand.
Deep-penetrated fertilizer is a combination of two types of fertilizer: nitrogen and potassium, mixed together, and pressed into pellets the size of plum seeds. After planting rice, farmers push the fertilizer pellets deep into the roots of the rice plants. During the rice growth process, the fertilizer dissolves, creating conditions for the rice roots to absorb. And even if there is heavy rain, the fertilizer will not be washed away like when spreading fertilizer. Applying deep-penetrated fertilizer is very favorable for rice production on terraced fields, so mountainous districts need to apply and replicate this model.
