The development of smart and eco-friendly fertilizers is pivotal to guarantee food security sustainably. Phosphate rock and struvite are promising alternatives for P fertilization; nevertheless, the solubility of these sources is a challenge for consistent use efficiency. Here, we propose using a polysulfide obtained via inverse vulcanization as a novel controlled-release fertilizer matrix in a system containing either Bayovar rock (Bay) or struvite (Str). The polysul ́ fide provides S for plants after being biologically oxidized to sulfate in soil, generating local acidity for P solubilization. After 15 days of soil incubation, the composites with 75 wt % Str and 75 wt % Bay achieved, respectively, 3 and 2 times the S oxidation from the elemental sulfur reference. Results indicated that P content stimulates the soil microorganismsʼ activity for S oxidation. The matrix had a physical role in improving Bay dissolution and regulating the rapid release from Str. Moreover, the available P in soil was 25−30 mg/dm3 for Bay composites, while for pure Bay, it was 9 mg/dm3 . |

The present artic1e summarizes the main aspects concerning the reproductive problems. related to milk and beef cattle as well as with buffaloes raised in the tropical areas of the world. Specific aspects which cause a low reproduction due to the genetic or hereditary condition as well as combined to the management and environrnental factors like heat stress, affecting mainly European breed originally from temperate climate areas, commonly introduced in the tropical areas, nutritional imbalances, reproductive diseases and other general systemic pathological condition which lead to sub-fertility, infertility or sterility and others constrains, were presented in practical form, pointing out the main problems which routinely, the Veterinary practitioner will find out in the tropical country conditions. |
