There are currently concerns within some sugar industries that long-term monoculture has led to soil degradation and consequent yield decline. An investigation was conducted in Swaziland to assess the effects of fallowing and green manuring practices

The von Mises equation was modified to describe numerically irregular distributions of leaf azimuth density. The new equation has three indexes: T (describing distribution elongation), S (describing number of azimuth preferences), and R (describing g

Evaporation from soil, Es, is important to land surface energy balance and has been estimated in many studies using a surface resistance approach. We investigate the accuracy of this approach using detailed measurement and simulation. Hourly evaporat
