Veris measures electrical conductivity. Sandy soil gives different readings than clay. U do 2 different depths so u can determine productivity of land in upper soil level and then lower levels. Veris also works better with wetter soil. Readings can be skewed if to dry. Our cost was 11 bucks an acre using RTK so it is more site specific and can also use for drainage purposes. Cost may vary on all that u are looking to find out, how wide u wanna grid the field and how smooth fields are. If smooth u can cover a lot of ground in a day. We did 700 in one day going 30 feet wide.

EC measures the amount of electricity conducted by soil.
Amount of moisture, amount of certain nutrients, salinity, alkalinity all have different readings.
The amount of moisture in a field will chancge the readings.
EC is also how you measure the amount of moisture in the soil, the wetter it is the higher the conductivity. I have sensors laying here somewhere...Comment

This is what $45 worth of EC equipment does.
One is an EC sensor, the other a salinity. Third one detects soil moisture.
The idea is to remove soil moisture and salinity from the mapping process.
