Castor Oil Cake is a byproduct derived from the seeds of the castor plant (Ricinus communis) after extracting its oil. This cake is rich in nutrients like nitrogen, phosphorus, and potassium, making it an excellent organic fertilizer for plants. It also has natural pesticidal properties that help control a variety of soil-borne pests and plant diseases. The high nitrogen content in castor oil cake aids in improving soil fertility and promotes vigorous plant growth.
Used widely in organic farming, it is an eco-friendly and biodegradable option that helps reduce reliance on synthetic fertilizers and chemical pesticides. Castor oil cake also boosts soil structure by improving water retention and nutrient availability, while promoting healthy microbial activity. Its cost-effectiveness and multi-purpose application in agriculture and gardening make it a sustainable choice for farmers.
