Changing of Sandy Soil Chemical Properties with Azolla microphylla and Quail Manure

Oleh: Syamsiah, Jauhari, Herawati, Aktavia, Mujiyo, Mujiyo

Uncontrolled land conversion causes reduced land area for plant cultivation. The alternative used for rice cultivation is the marginal land such as sandy soil, however, several constraints led to very low productivity, so it needs proper management such as the addition of organic matter. The purpose...

Release Pattern of Nitrogen and Potassium from Controlled Release Fertilizer (CRF) in the Soil

Oleh: Suwardi, Suwardi, Suryaningtyas, Dyah Tjahyandari, Saputra, Hens

Nitrogen (N) and potassium (K) are macronutrients that plants need for better growth and yield. However, they are readily lost from the soil through volatilization, denitrification, and leaching, aside from being absorbed by plant roots. Thus, a Controlled Release Fertilizer (CRF) may be formulated ...
