Fertilizer And Limestone Applications After The Harvest Of Sugarcane As Determined By Geostatistics Techniques [aplicação De Adubo E Corretivo Após O Corte Da Cana-planta Utilizando Técnicas Geoestatísticas]

Knowing the spatial variation of soil properties can contribute for planning and optimization of experiments and commercial crops based on precision agriculture. The objective of this research was to evaluate the necessity of fertilizer and limestone applications for the implantation of precision agriculture techniques based on the spatial behavior of chemical attributes of one Latosol after the harvest of the sugarcane. The data were evaluated by means of descriptive statistics and spatial dependence analysis with the adjustment of semivariograms. The geostatistics techniques applied were found to be suitable as auxiliary tools in the fertilizer application by means of variable rates. It was detected that phosphorus and limestone applications were not necessary according to the variable rate.
