The consensus of soil fertility specialists working in the northeast USA was that soil testing and recommendation systems for P needed to be reexamined because of recent changes in soil testing methodology in the laboratory and corn (Zea mays L.) pro

Soil P saturation affects the risk of P loss to surface and ground water and is therefore a critical environmental indicator in regions where eutrophication is a concern. In the USA, most soil testing laboratories do not include environmental indicat

The progress that has been made so far in all aspects of tractor, implement control is hard to believe and yet the completely autonomous tractor, implement system that can work on contiguous farm property is still a long way from reality. This is pri

We investigated the efficiency with which a laboratory robot is able to extract available nutrients from soil contained in tubes. We have shown that for vortex mixing, the volume of soil and extractant are of critical importance. In cases where the s

A commercial laboratory robot has been used to compare the responses of two different types of electrode for the determination of soil in water pH (pHw), and soil in SMP buffer solution pH (pHSMP). The latter is integral to a popular method for the d

A commercial laboratory robot has been programmed to aid in the determination of soil lime requirement. Soil samples submitted to our laboratory, after drying, grinding, and sieving, are manually scooped into racks of pre‐weighed glass tubes. From

Maize (Zea mays L.) forage producers need more information on how N management affects dry matter (DM) yield, forage quality, and residual soil NO 3 − -N concentrations. Studies were conducted in New York to evaluate three hybrids under different s
