| dc.description.abstract1 | The least limiting water range is a soil physical quality indicator, which is useful to
predict the optimum water range for plant growth in a given soil and to study the effects of soil
use and management over this optimum water range by integrating the effects of available water,
penetration resistance and air filled porosity. This study tested six equations to fit water retention
and penetration resistance surface responses used to determine the least limiting water range
and present a simple algorithm written in the open source software R for fitting, calculation and
visualization of the least limiting water range. Five soils from Brazil and Canada, under different
use and management conditions were used to test the functions. The results show that the three
water retention surface responses had good statistical properties for fitting water retention and
that two of the penetration resistance surface responses were adequate to fit the data, while
one failed to achieve convergence in two instances. The open source code performed as well as
the commercial statistical package SAS for fitting the penetration resistance and water retention
equations. | pt_BR |
