To estimate soil water content, samples should be taken from what depth?

To estimate soil water content accurately, it is essential to take samples from the depth specified by the product label. Product labels provide crucial information regarding the effective application depth for chemicals and treatments. This depth is tailored for optimal performance of the product, where soil moisture levels significantly influence its efficacy.

Sampling at this designated depth ensures that the readings reflect the soil water content that the product will interact with during application, leading to more precise calculations and better outcomes in pest management or soil health assessments. Sampling from the surface layer, any random depth, or below the root zone might not provide relevant data regarding the conditions essential for effective treatment, thereby rendering estimates unreliable.
