Organic manure
जैविक खाद
In Class 9 Agriculture, under the chapter “Manure and Fertilizers,” students learn how organic manure is prepared from decomposed plant and animal materials and how it supports crop growth. They explore common forms such as farmyard manure, compost, green manure, and vermicompost, along with their role in supplying nutrients, improving soil structure, increasing moisture retention, and encouraging useful soil microorganisms. The topic also helps students understand proper application and the value of recycling biodegradable farm and household waste.
