| 實物特徵: | A linear programming model was used to minimize the cost of higher nutrient fertilization, N, P, K, Ca and Mg, in order to seek ways to improve the competitiveness of horticultural crops like carrot cropping. The minimum cost obtained was US $ 1,601.79 per hectare, with the use of 714.19 kg /hec of 10-30-10, 1026.81 kg /hec of 15-3-31, 401.79 kg/hec of 15-15-15, 244.12 kg /hec of magnesium sulfate and 525 kg /hec of calcium carbonate. The defined target yield was 50 t / hec. These results contrast with traditional fertilization in the area under study, where is common the use of a few source of fertilizers. |
