Оптимизиране на калиевото торене при ранно и средноранно производство на домати за устойчиви добиви и икономическа рентабилност
Веселина Василева
Abstract: Дробното калиево торене се явява ефективен метод за удължено приемане на съизмерими през вегетацията количества достъпен калий, чрез който да се поддържа положителен калиев баланс в почвата, но и да се реализира по-висок добив и качествена продукция. Целта на проучването е да определи икономическата ефективност от разделянето и дробното внасяне на калиевата норма при отглеждането на домати като ранно и средно-ранно производство. Резултатите в проучването показват, че доматените растения използват оптимално калия, при разделянето и дробното му внасяне, като по този начин е постигнат по-висок добив и общ приход от продукцията. Вариантите с дробно торене са икономически изгодни, а вариант N24Р12К8+8+8 се оказва особено подходящ при ранно полско производство на домати. Настоящият анализ подчертава важността от оптимизацията на торенето в селскостопанските практики у нас, потенциала за повишаване на икономическата ефективност и печалбата за земеделските производители, и устойчивото използване на почвените ресурси.
