Description
Summary:This study aims to determine the status and stock of soil nutrients in three types of land ownership management. This research was conducted on smallholder farmers (SF), tenant farmers (TF), and owner farmers (OF) in Kuranji District, Padang, West Sumatra, and at the Soil Laboratory of the Faculty of Agriculture, Andalas University from March to September 2022. The range of nutrient status in the three types of land ownership is 0.06-0.35% C-organic and 0.06-0.13% N. The concentration ranges of Ca, Mg, K, Na, P, and Si, respectively, were 0.52-0.79; 0.58-1.34; 0.07-0.12; 0.03-0.09 cmol.kg-1and 2.52-12.7; 31.73- 49.33 ppm. The results showed that each management type’s status of organic carbon in soil was deficient. This result was presumably due to miss management of straws. The highest concentrations of Ca, Mg, K, and Na were found in smallholder farmers’ fields (SF), while the lowest concentrations were found in tenant farmers’ fields (TF). The stock of soil nutrients shows a similar trend to the nutrient status of the soil. The dose of fertilizer by SF and TF was 129.5 kg/ha N; 37.5 kg/ha P2O5; 37.7 kg/ha K 2 O, while OF is 176 kg/ha N, 65 kg/ha P 2 O 5 , 45 kg/ha K 2 O. The soil nutrient status among the farmer groups is not significantly related to the amount of fertilizer application. It is recommended to give a dose of fertilizer following the recommendations that have been set and balanced with the proper management of remaining straw after harvest for sustainable soil fertility and agriculture production.
