What happens when you grow the same crop over and over again in the same field
irinina [24]
Well there's a couple reasons why. First, the land itself can become “tired" and less fertile<span>. This is because the same type of </span>crop<span> planted repeatedly in the same area keeps draining the land of the same nutrients needed for that plant's growth. Pest can also plant their nest near the crop if the farmer continues to plant the same crop in the same place. 

Which is the reason why things such as "crop rotation" exist to keep things fresh, and prevent what I described above from happening.</span>

Selected Answer: alpha particle
Lostsunrise [7]

Answer:

positron

Explanation:

A positron is a particle produced when a proton is transformed into a neutron. Anti neutrinos are ejected from the nucleus to balance spins.

Positron emission increases the Neutron/Proton ratio. When a nuclide undergoes positron emission, the atomic number of the daughter nucleus is one unit less than that of the parent nucleus hence it is found one place before its parent in the periodic table.
