Solar irrigation pumps: can electricity buy-back curb groundwater over-use? por Franklin, Bradley

“…As solar irrigation pumps become more effective and affordable, the prospect of uncontrolled solar pumping further exacerbating the unsustainable use of groundwater has led to calls by some for the government to buy back excess electricity generated on farms. Under such a scheme, the buy-back price would have to be high enough to make selling the power more profitable than using it for further irrigation, yet not as high as the price that is charged for electricity from the grid lest an opportunity for arbitrage be created. …”

C and N stocks are not impacted by land use change from Brazilian Savanna (Cerrado) to agriculture despite changes in soil fertility and microbial abundances por Lammel, D.R., Butterbach-Bahl, Klaus, Cerri, C.E.P., Louis, S., Schnitzler, J.P., Feigl, B.J., Cerri, C.C.

“…Even if these changes can be beneficial for food and agricultural commodities production, all these soil alterations should be further investigated due to their possible unknown effects on biosphere–hydrosphere–atmosphere exchange processes such as greenhouse gases emissions and nitrate leaching.…”

Genotype environment interactions for cyanogenic potential in cassava por Bokanga, M., Ekanayake, I.J., Dixon, A., Porto, M.

“…A high ground water table with an associated low water stress to the developing cassava roots does not necessarily lead to lower cyanogenic potential. Excess water stress created by an above ground water table leads to higher cyanogenic potential. …”

The Activity of the Chloroplastic Ndh Complex Is Regulated by Phosphorylation of the NDH-F Subunit por Lascano, Hernan Ramiro, Casano, Leonardo M., Martı́n, Mercedes, Sabater, Bartolomé

“…In the present work, we have compared the effects of relatively excess light, H2O2, dimethylthiourea (a scavenger of H2O2), and/or EGTA (a Ca2+chelator) on the activity and protein levels of the Ndh complex of barley (Hordeum vulgare cv Hassan) leaf segments. …”

State of knowledge in tiller dynamics por Matthew, Cory, Agnusdei, Monica Graciela, Assuero, Silvia Graciela, Sbrissia, André F., Scheneiter, Jorge Omar, Silva, Sila C. da

“…Fundamentally, when a pasture does not persist the problem can be expressed in terms of inadequate new tiller production or excessive tiller death. However, the collection of data to build an understanding of sward dynamics at this level is time consuming. …”

Different pig slurry application methods modify the soil quality and increase the productivity of winter wheat (Triticum aestivum L.) Crop (Córdoba, Argentina) = Diferentes métodos... por Pegoraro, Vanesa Romina, Mir, Leticia Raquel, Briacchi, Martina, Bachmeier, Omar, Ortiz, Jimena, Lorenzon, Claudio Antonio, Hang, Susana, Zubillaga, Marta Susana

“…In Argentina, slurry surface application is the technique most used, although with high risk of ammonia losses. These emissions can be reduced by using different application methods, but their impacts on the soil-plant system have been little explored. …”

Volatile organic compounds characterized from grapevine (Vitis vinifera L. cv. Malbec) berries increase at pre-harvest and in response to UV-B radiation por Gil, Mariana, Bottini, Ambrosio Rubén, Berli, Federico Javier, Pontin, Mariela Ana, Silva, Maria Fernanda, Piccoli, Patricia Noemí

“…These results along with others from the literature suggest that UV-B induce grape berries to produce VOCs (mainly monoterpenes) that protect the tissues from UV-B itself and other abiotic and biotic stresses, and could affect the wine flavor. Higher emission of monoterpenes was observed in the field experiments as compared in vitro, suggesting the UV-B/PAR ratio is not a signal in itself.…”
