Abstract: The effect of osmolality of skim-milk diluents (200, 320, 450, 600, and 750 mOsm/kg water) on the survival of ram spermatozoa frozen in straws were investigated after thawing in 39 °C water or in 20 °C air. Spermatozoa motility improved with increasing osmolality of the freezing diluent, irrespective of thawing rate. Diluents of 600 and 750 mOsm resulted in highest motility immediately after thawing and after 60 min incubation at 39 °C. A significant decrease in spermatozoa motility was observed when straws were thawed at 20 °C air with the magnitude of decrease inversely related to osmolality of the freezing diluent. Fertility of progestagen synchronized ewes inseminated with semen frozen in the 600 mOsm hypertonic skim-milk diluent was comparable to that obtained with fresh semen. |

Abstract. Phosphorus availability in the soil is essential for plant growth. In Brazil, phosphorous is poorly available in the soil due to its high adsorption in the form of phosphates. This phenomenon requires much studying to assist in the nutritional management of crops. To that end, predicting the fraction of adsorbed phosphorus can be approximated by using attributes that influence soil formation and structure. This study aimed to predict soil phosphorus adsorption based on soil attributes in sugarcane crops with different relief types using data mining techniques. The experiment was carried out in sugarcane agricultural areas, experimental plots with differentiated relief (concave or convex), and identical agricultural practices. The soil was classified as an Alfisol with udic moisture (Udalf) regime and medium to clayey texture. The dataset constituted a matrix of 4580 observations. The analyzed variables corresponded to the chemical, physical, geophysical, and mineralogical attributes in the 0-0.2 m topsoil. Data analysis was carried out based on a decision tree induction model, with an 85% accuracy rate and a high level of agreement between variables. The decision tree recognized magnetic susceptibility as the attribute with the most significant influence on the prediction of soil phosphorus adsorption, validating the relation among adsorption processes and the magnetic properties of oxide minerals characteristic of Brazilian agricultural regions. |
