Farmyard fertilizers also need to prevent nutrient losses
At present, many rural households are aware that improper storage or use of chemical fertilizers like urea and ammonium carbonate can lead to significant nutrient loss. However, they often overlook the importance of managing farmyard manure properly, which is actually one of the most valuable sources of organic fertilizer in rural areas. This neglect leads to a substantial waste of nutrients, reducing the effectiveness of natural fertilizers.
For instance, some farmers have poorly maintained livestock sheds that are leaky and prone to water seepage. As a result, the urine and manure mix with rainwater, causing nitrogen to evaporate and nutrients to be washed away. In other cases, farmers pile up manure in open areas, leaving it exposed to wind, sun, and rain. This exposure causes the nitrogen in the urine to escape as gas, while dissolved nutrients drain away with the water, resulting in poor-quality manure. Studies have shown that if animal urine is not properly managed, up to 96% of the nitrogen can be lost within just a month and a half. Therefore, it's crucial for farmers to pay more attention to how they store and handle farmyard manure.
To minimize nutrient loss from livestock manure, improving the structure of the manure pit is essential. The pit should be waterproof and airtight to prevent leakage and ensure better retention of nutrients. It’s also recommended to mix the excreta with soil in a ratio of 1:3 to 1:4, and cover it daily or every other day. If the manure isn’t used immediately, the pit should be sealed with mud to maintain its efficiency.
When it comes to human urine, which is rich in nitrogen, phosphorus, and potassium, it’s important to store it properly. If left untreated in an open container for 60 days, nearly 90% of the nitrogen can be lost. To reduce this loss, urine should be stored in a covered tank or container, ideally for 7 to 10 days to limit the time it’s exposed. This helps preserve its nutrient content.
For human feces, the key is to ensure that toilets and septic tanks are sealed and protected from leaks and rain. Additionally, when applying feces to the soil, it should be diluted first. In summer, the decomposition time is about 6 to 7 days, while in other seasons, it may take 15 to 20 days. It's also strongly advised to separate human waste from other types of manure to avoid nutrient imbalances.
Regarding plant ash, which contains a high concentration of potassium carbonate, it is one of the few alkaline fertilizers found in farmyard manure. When mixed with acidic organic materials like human waste, the acid-base reaction can cause nutrient loss. Research shows that storing grass ash and human waste together in a 1:1.5 ratio for 10 days results in about 27.4% nitrogen loss, and after three months, the loss can reach 85.9%. Therefore, it's best to store and use grass ash separately, without mixing it with other organic fertilizers. Farmers should also protect ash from rain to prevent nutrient leaching.
By implementing these practices, farmers can significantly improve the quality and efficiency of their organic fertilizers, leading to better crop yields and more sustainable farming.
