Family Vegetable Gardening - Continuous Soil Improvement
Sharing knowledge about fruits and vegetables, family vegetable gardening - continuous soil improvement, next, the editor will introduce.
For successful urban balcony (roof) gardening, the first issue is soil. Soilless cultivation is one aspect, but both involve cost and technical issues. Many people still use soil cultivation. It's good to buy and use better garden soil, but it still involves cost issues, especially if the area is larger (for example, over 10 square meters) it would require over a thousand jin of soil. In this case, without planning to invest more, one can only rely on their own methods.
Nowadays, especially in big cities, there is a lot of construction on the roads, everywhere is being excavated. There is plenty of soil, but the problem is that the quality of the soil for gardening is very poor. The only way is to continuously transform (improve) the soil during the planting process. The fertility of the soil also continues to improve, and after a few cycles, we can reach our goal.
My soil and soil additive sources are mainly:
1. Soil from the excavation of urban viaduct construction;
2.塘泥 from the excavation of the Donghu Tunnel construction;
3. Purchasing a small amount of substrate (nutrient-rich soil);
4. Sand (leftover from roof waterproofing maintenance);
5. A large amount of kitchen waste;
6. A large amount of fish intestines (there are plenty where you buy fish at the market);
7. A large amount of soybean dregs (available from places making soy products);
8. Straw after harvest (such as chili, tomato, vegetable seedlings), etc.
My method is to completely remove all the soil after harvesting (including the roots), and then put the ready-to-compost messy stuff at the bottom and refill with crushed soil. I'm not too worried about the issue of roots burning from continued fermentation. I think the amount of mixture each time is not much and it won't heat up like composting. The refilled soil also has a certain depth, and by the time the roots grow to the bottom, the messy stuff is almost rotten. If you're not comfortable with it, watering is also a solution, anyway, you have to water!
Of course, to help the plants grow, it is necessary to add some basic fertilizer (such as dried chicken manure) to the refilled fine soil.
Currently, a considerable part of the soil I use for roof gardening has been improved, and the rest will continue to be transformed.
The following pictures show the process of refilling soil in two foam boxes and transplanting lettuce seedlings today:
The above sharing is a comprehensive introduction to family vegetable gardening - continuous soil improvement, hoping to bring some related knowledge of green plants to green plant enthusiasts.
