In the last few years, more and more fruit farmers and growers of both wine and table grapes report frequent internerval chlorosis of the younger leaves, which subsequently result in necrotic spots with early leaf drops and bring to progressive qualitative and quantitative production losses.
The phenological phases that go from setting (formation of the embryo) to the beginning of fruit growth are extremely delicate, since the correct nutritional balances play a fundamental role for the obtainment of qualitatively and quantitatively satisfactory productions for farmers. It is especially important in these phases to guarantee to the crops full availability of …
Blossom end rot (BER) is one of the most common physiopathologies in crops such as tomatoes and other solanaceae (e.g. bell pepper). The physiopathology brings both morphological and chromatic malformations in the fruits. The damage normally appears in the form of a lesion in the distal apex of the fruit, due to the necrosis of …
Frost and temperature drops in spring represent the main challenge for world agriculture. In Europe, an intense increase in spring frosts has been registered in the last decade: these affect all of Europe and in particulr the Balcanic area, even though climate change is currently bringing a general rise of temperatures. At this time of …
In order to optimize and improve fertirrigation interventions and preserve the facilities, it is necessary to neutralize the content of bicarbonates (of calcium and/or magnesium) present in irrigation waters, considering the worsening quality of water itself. The acidification of the water used in fertirrigation increases the solubility and the availability of nutrients and is a …
The in-barrel preparation of the sprayable solution requires the observance of a specific sequence of product dilutions, in order to guarantee their best stability and dispersion, avoiding thus the formation of precipitates or suspensions, fundamental aspects to reach the expected efficacy. The correct sequence is the following: 1.Pour first Vyrer, water pH regulator 2.Mineral fertilizers …
More and more, in recent years, seasonal critical conditions are leading both a poor development of the cereals during the winter months and a poor spring tillering that negatively affect the productivity and the quality of the crop.
Nell’emisfero boreale l’inverno è ormai alle porte ma in alcune aree geografiche la stagione tipicamente più fredda è in realtà caratterizzata da temperature piuttosto miti che possono influire in modo significativo sulla produzione delle colture.
The problem of salinity of the soil concerns more than 7% of the SAU of the planet. The causes include: low quality and availability of irrigation waters, the lowering of the groundwater due to its excessive exploitation, unbalanced fertilization, superficial processing of the ground and alkalinization of the soils with consequent reduction of the availability …
Seedlings transplanting from nursery to the field has several advantages if properly managed through targeted treatments that promote crops rapid vegetative growth. Growth of the root system and vegetative growth. To support root system growth, starting from the first fertigation after transplanting, every 15- 20 days, it is necessary to adopt a strategy that alternates …
