| Popis: | Boron deficiency in the soil is commonly found throughout the country, mainly in cerrado soils, making it extremely necessary to fertilize such a micronutrient. Therefore, this study aimed to evaluate the availability of boron in clay and sandy soils with different sources of borated fertilizers in soybean cultivation in the 2018/19 soybean harvest. The availability of boron was evaluated by the method with hot water extraction in a soil sample in different soil layers and at a different time of collection. The experiment was assembled in randomized blocks (DBC), with 5 treatments and 4 replications, as follows: split boric acid: twice, total boric acid: one application of the integral dose, Granulex ®️, Produbor®️ and control treatment Granulex provided higher B content in the soil in the 1st collection, in the 10-20 cm layer in cl In sandy soil, the different sources did not defer under the availability of B at all depths and collections. In general, clayey soils retain B more when compared to sandy soils |
