Shin Woncheon, along with Ryu Hyunwoo and Ra Jinho, took their bowls back to the kitchen for cleaning, while Gang Yuwon followed Kim Haru outside to check on the fire.

The pile of soybean stalks that needed burning had already turned to ash, leaving only a mound of black-gray residue.

[ Ding! Homemade <<Basic Fertilizer: Wood Ash>> has generated a crafting blueprint.]

[ Ding! Congratulations you have obtained the blueprint: Wood Ash Fertilizer.]

Oh, a surprise!

Kim Haru opened the blueprint, revealing the crafting steps, which included burning the plant material and adding a crystal core.

In order to make a batch of ten units of fertilizer, one crystal core was required.

The previous basic fertilizer provided by the system had also needed a crystal core in addition to various manures, decayed leaves, and leftovers from the kitchen to create the compost.

The explanation given in the blueprint stated that the wood ash fertilizer made with crystal cores, as per the system's crafting page, would be more effective than the plain wood ash fertilizer he could burn by himself. It could be applied directly to crops, regulated by the system, preventing situations where there was too much or too little fertilizer, which could lead to uneven plant growth.

It would also eliminate the risk of killing the plants.

Kim Haru had indeed heard about this. If too much fertilizer was applied without proper control, the plants could become over-nourished and end up dying from nutrient overload.

The crystal cores required for the fertilizer had no specific attributes. Kim Haru picked up a wooden stick and extracted the burned potatoes from the ash, then added fifteen crystal cores directly into the mix.

Before long, one hundred and fifty units of wood ash fertilizer were laid out in front of him.

That afternoon, Kim Haru led Shin Woncheon and the others to coat the fifty cut potato pieces with wood ash, placing them into the plots, covering them with soil, and sprinkling the remaining fertilizer on top.

One hundred soybean seeds were also planted, one seed per hole, followed by another layer of fertilizer.

Actually, it would have been fine to apply the fertilizer first and then cover the seeds with soil, but Kim Haru worried he might forget which spots had fertilizer and which did not, so he decided to spread it over everything.

Anyway, it all worked out,

After sowing the second batch of seeds and watering them, Kim Haru was finally ready to set off.

He didn't have much thing to take, just nine large cabbages, with one weighing an impressive six pounds, meaning he had over fifty pounds of cabbage alone. The soybean yield was also fantastic, with each plant producing about half a pound; he used some as seeds and still had over four pounds left. The potatoes, of course, were the heaviest of all.

Each potato plant yielded around fifteen potatoes, with the larger ones weighing over two pounds, even reaching three pounds. The smaller ones weren't much lighter either, so the total yield per plant was at least thirty pounds.
