Abstract: The effects of three commercial conditioners on available water, water conserved, and crust strength of a loamy sand soil (Typic Torripsamments) were investigated. The conditioners used included Agromousse (AGR), Perlite (PER), Peters (PET), and a mixture of equal amounts of PER and PET (PERT). Treatments consisted of two irrigation intervals: 7 and 14- days, and four rates for each conditioner: 0. 0.5, 1, and 2 times the rate recommended by producers (RC). The RC rates were 0.6, 4, 8, and 6 % for AGR, PER, PET, and PERT, respectively. The application of RC, PER, PET, and PERT increased soil available water (AW) but did not significantly affect the amount of water conserved (WC) by the end of the 14- day cycle. Agromousse at this rate did not significantly affect soil AW but increased WC in both intervals. All conditioners applied at double RC substantially increased soil AW, but to a less extent reduced WC by the end of the fourth 7-day cycle. Furthermore, this rate did not significantly affect WC by the end of the 14- day cycle. The addition of all conditioners increased the modulus of rupture of the soil but not to the level that causes crusting problems.
