| Popis: | This research on the escalation of nutrient status aims to determine the effect of giving Terra Preta Biochar Padi (Tetadi) on ex-gold mining land to P-available land in Nagari Padang Sibusuk Sijunjung Regency, West Sumatra. Soil samples were taken from the former gold mining soil with a depth of 0-20 cm randomly. This research was conducted using a completely randomized design with 6 treatments and 4 replications consisting of control (A), Tetadi 10 tons / ha (B), Tetadi 15 tons / ha (C), Tetadi 20 tons / ha (D), Tetadi 25 tonnes / ha (E), and Tetadi 30 tonnes / ha. The results showed that giving Terra Preta Biochar Rice to ex-gold mining land could increase the highest available P of soil in the treatment of rice Terra Preta Biochar 30 tonnes / ha with the results of the 5% DMRT statistical test very significantly different from the control treatment and 10 tonnes / ha and 15 tonnes / ha. Soil pH also showed the highest increase in the treatment of 30 tonnes / ha with a pH value of H2O of 5.7 and followed by a pH of KCl with a value of 4.6 and statistical test results showed that the treatment of 30 tonnes / ha was also very significantly different from control and treatment. |
