In all those areas where the strawberry is intensively grown, the cases of reduction in production both from the qualitative and quantitative point of view, often generically attributed to phenomena of "soil fatigue", are particularly serious. In fact, the reasons that can explain the reduction in the production of strawberry fields are manifold and, of course, among them we must remember the presence of pathogenic fungi, weeds, insects and parasitic nematodes harmful to the crop. Soil fumigation allows drastically reducing the potential inoculation of the main pathogens and pests in the soil (Pythium spp., Phytophthora spp., Verticilliumdahliae, Rhizoctonia solani and Fusarium spp., Macrophomina spp., Meloidogyne spp.), controlling weeds and increasing the availability of nitrogen thanks to the mineralization of the organic matter.
Soil disinfection and integrates alternative strategies
An estimate of the importance of soil fumigation in Italy was conducted thanks to a complex technical-economic study developed by Nomisma in 2008. This study analyzed the state of the global use of fumigants in Italy in the most intensive (monocultural) sectors of national horticulture, tracing out a series of possible scenarios with way of a simulation of the progressive unavailability of chemical fumigants. This study essentially confirmed the close dependence of intensive horticulture on the use of fumigants, foreseeing a significant contraction of the gross saleable production in the event of a total elimination of the use of these substances in the absence of an adequate substitution through alternative strategies or solutions.
Due to the above reasons, from a future perspective, it is essential to start working from today on alternative strategies to the use of these substances.
Alternative solutions for a good planting of young seedlings
1. The seedlings already mycorrhized have a stronger, more extensive root system, able to better withstand the stress related to planting and to absorb water and nutrients with greater efficiency. Also important is the use of a good organic substance when preparing the the soil, which improves the soil structure and liveability for the plant, in addition to enriching it with beneficial microbial flora.
2. In cases where no already mycorrhized seedlings are used in the nursery, it is possible to make use of mycorrhization in the field, which, in any case, has considerable benefits and allows obtaining stronger and more resistant plants.
3. The use of a good root formation stimulator is essential to overcome transplantation-related stress and to help the plant develop a good root system in view of production.
A healthy plant, with a good root system, in a soil rich in quality organic matter can give good productions, even when it is not possible to fumigate the soil.
Agriges strategy fertilization strategy
When preparing the soil, TRIONEM. A revitalizing basal fertilizer for tired and impoverished soils, especially designed to increase their long-term fertility. It is a product based on precious raw materials of vegetable (Bassicaceae, Meliaceae and Liliaceae) and animal origin. Activated by the following bacterial strains: Thermoactinomyces spp., Streptomyces spp. and Bacillus spp., obtained through the exclusive MICROZYMTRIO production technology, are the ones responsible for guaranteeing the high and constant effectiveness of TRIONEM against soil fatigue. TRIONEM revives the soil, rebalances its microbial component and nourishes the plant with harmony. Agriges recommends its application before solarization in order to maximize its effectiveness and improve the soil liveability.
In post transplantation, TRI-START CREAM. A cream product of microbiological origin obtained through the special MICOTECH production technology, which is characterized by the presence of a carefully selected microbial consortium containing plant growth promoting bacteria, mycorrhizae, fungi and actinomycetes: biopromotors and inducers of endogenous plant resistance.
The MICOTECH microbial consortium is the result of a long cooperation between Agriges research and development department and important research centres.
MICOTECH contains: mycorrhizae of the genus Glomus spp., rhizobacteria of the genus Azobacter spp. and Bacillus spp., a selection of fungi and actinomycetes including Trichoderma spp. and Streptomyces spp.
1. The endophytic mycorrhizae of the genus Glomus spp. develop inside colonised plant cells and guarantee a greater surface of root absorption and greater absorption of nutrients, in particular of phosphorus.
2. The growth promoting microorganisms of the genera Azobacter spp., Bacillus spp. and Streptomyces spp. colonise the rhizosphere and the plant itself (the endophytic ones) and promote the development of the latter through the production of phytohormones, siderophores (iron-chelating compounds with low molecular weight), and volatile phytostimulanting compounds, and through nitrogen fixation.
3. The microorganisms contained in MICOTECH occupy the ecological niches of pathogenic microorganisms, thus preventing their propagation. In addition, the presence of Trichoderma spp. stimulates the induced systemic resistance of the plant, which reacts by setting up physical barriers and producing antimicrobial substances.
To promote rooting, the bioactivator RYZORAL FLOW, obtained from organic matrices of several plant essences that contains Brassinosteroids, i.e. root development promoting plant hormones. RYZORAL FLOW contains also RyZea, a production technology that involves the extraction of the biostimulant compounds from the seaweeds Ascophyllum nodosum, Fucus and Laminaria. RYZORAL FLOW is in liquid form and contains Nitrogen in organic, nitric and ammoniacal form; in addition to Zinc, it contains microelements such as: Boron, Copper, Iron, Manganese, and Molybdenum.
