Castor bean base fertilizer effect

Base fertilizer refers to the fertilizer applied before sowing castor seeds. There are two main functions of applying base fertilizer:

The first is to increase soil fertility and create good soil conditions for the growth and development of castor beans;

The second is to provide sufficient nutrients for the growth and development of castor beans, so that castor beans can absorb and replenish sufficient nutrients in time after germination.

How to apply castor bean base fertilizer

1. Broadcasting

That is, before plowing the soil, spread the fertilizer evenly on the ground, and then plow the fertilizer into the soil to fully integrate the fertilizer and soil, which is very beneficial to comprehensively improve soil fertility. The deeper the base fertilizer is applied, the greater the nutrient supply of castor beans in the later growth period.

2. Strip application and hole application

That is, before sowing, combine land preparation, apply fertilizer into the soil by digging furrows or holes, and then cover the soil and sow seeds. This is a kind of concentrated fertilization, which is more effective, but be careful not to apply excessive amounts of fertilizer.

How to apply base fertilizer to castor beans

If you are remediating on barren land with little base fertilizer, you need to apply topdressing twice, adding no more than 7.5 kg of urea per mu each time during the seedling establishment period and the fruit cluster formation period.

If you are applying fertilizer to a plot with good fertility, you should do it when the main stem inflorescence has just sprouted and combined it with riveting the soil. But no matter when you apply fertilizer, the fertilizer must be buried deep, so as to ensure that castor can grow healthily.
