2. Water extraction and implications on soil moisture sensor placement in the root zone of banana
ABSTRACT: The knowledge on spatial and temporal variations of soil water storage in the root zone of crops is essential to guide the studies to determine soil water balance, verify the effective zone of water extraction in the soil and indicate the correct region for the management of water, fertilizers and pesticides. The objectives of this study were: (i)

3. Association of swine wastewater and mineral fertilization on black oat production
ABSTRACT Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The o

4. Water extraction variability in the banana root zone affects the reliability of water balance
Spatial and temporal variability of soil water extraction from the root zone affect soil water balance determination. The number of sensors installed in the root zone in studies addressing water balance is still set arbitrarily. This study provided an investigation of the water extraction process by banana (Musa spp.) roots by (i) determining the variability

6. Effects of fertirrigation with effluent of primary treatment of wastewater from swine on the soil and in the productivity and quality of tomato (Lycopersicon esculentum Mill.) / Efeitos da fertirrigação com efluente do tratamento primário da água residuária da suinocultura no solo e na produtividade e qualidade do tomate (Lycopersicon esculentum Mill.)
In this study was analyzed the effects of fertirrigation with filtrated wastewater from swine (FWS) on soil and the physiological, sanitary variables and of tomato production, in drainage lysimeters under protected environment. The experiment was carried out in the lysimeter station at the Hydraulic, Irrigation and Drainage Experimental Area, in campus of th

7. Estudo fÃsico-hÃdrico em lisÃmetros e comparaÃÃo de elementos climÃticos na regiÃo de Lavras - MG / Physical-hydric study in lisymeters and comparison between climatic elements at the region of Lavras, MG,
This work aimed to compare data obtained from conventional (EMC) and automatic (EMA) meteorological stations, and to compare different methods against the standard method for estimating the reference evapotranspiration (ETo), for the region of Lavras, Minas Gerais, Brazil. The EMC data, between 2005 and 2008, were obtained from National Institute of Meteorol

8. Análise da evapotranspiração de referência a partir de medidas lisimétricas e ajuste estatístico de estimativas de nove equações empírico-teóricas com base na equação de Penman-Monteith / Analysis of the reference evapotranspiration from lysimetric data and statistical tuning of nine empiric equations based on the Penman-Monteith equation
The quantification of the evapotranspiration is an essential task for the determination of the water balance in a watershed and for the establishment of the culture´s water deficit. Therefore, the present work describes the analysis of the reference evapotranspiration (ETo) for the region of Jaboticabal-SP. The phenomenon behavior in the region was studied

9. Tebuthiuron herbicide behavior in sugar cane soil using modified drainage lysimeter / Comportamento do herbicida tebuthiuron em solo de cultivo de cana-de-açucar utilizando lisimetro de drenagem modificado
Tebuthiuron is one of the most used herbicides in sugar cane, in São Paulo State. Studies have been carried through to determine the tebuthiuron leaching index and to monitor its presence in superficial and groundwater sources, without still a definitive conclusion. With the objective to evaluate, in field conditions, the vertical movement of the herbicide
