"Proper use and control of NOx in greenhouse can increase yield"
It is well known that CO2 contributes to a good growing crop. It is also known that NOx, a gas that is produced during incineration such as in CHPs, is harmful to the crop. But research now shows that small amounts of NOx can actually increase yield. A remarkable conclusion, says Jacco Besuijen. He is an…
Using digestate and biochar as fertilizers to improve processing tomato production sustainability
The principal goal of the organic farming system (OFS) is to develop enterprises that are sustainable and harmonious with the environment. Unfortunately, the OFS yields fewer products per land than the non-organic farming system in many agricultural products. The objective of a new study was to assess…
First bean harvest on martian and lunar soil fertilised with urine
Since November 2019, Wageningen University & Research has been experimenting with the cultivation of string beans on artificial martian and lunar soil. What makes this experiment so special is that part of the crop is fertilised with human urine in the form of struvite. The main question is: does this…
Interactive effects of CO2 enrichment and nitrogen supply on cucumber plants
The concentration changes of mineral elements in plants at different CO2 concentrations ([CO2]) and nitrogen (N) supplies and the mechanisms which control such changes are not clear. Hydroponic trials on cucumber plants with three [CO2] (400, 625, and 1200 μmol mol−1) and five N supply levels (2, 4, 7,…
Trichoderma-based biostimulants in greenhouse leafy vegetables
A new study addresses the effects of Trichoderma-based biostimulants and nitrogen (N) fertilization levels on agronomic performance and functional quality of two important…
New fertilizer treats and prevents calcium deficiency in organic crops
BioWorks has launched ON-Gard Calcium, an organic liquid fertilizer with plant derived protein hydrolysate and calcium chloride for the treatment and prevention of calcium deficiency in organic crops. The calcium formulated fertilizer increases the uptake efficiency of calcium by plants at reduced application…
Worm fertilizer: from organic waste to bio-stimulant
Millions of red worms crawl through the long sterile trays in the compost factory of Vermis Organik in Izmir. These remarkable worms compost vegetal waste. 'Mini-factories' is what Benelux sales manager Saban Bozalie call the red Californian worms, names Eisenia Fetidaze. "The life on the surface of the…
Russian scientists studied the effect of selenium on the properties of basil
A team of scientists from Immanuel Kant Baltic Federal University discovered that micromolar selenium doses increase the levels of useful biologically active compounds in the leaves of sweet basil. The results of the study may be used by agricultural enterprises to improve the quality of their products.…
Effects of water stress and modern biostimulants on mint
Natural biostimulants combine different elicitors that may influence economic properties of herbal crops, such as mint. In a new study, mint (Mentha longifolia L.) plants were subjected to three water levels based on container substrate capacity (CSC; 100% CSC, 70% CSC, and 50% CSC) and/or applications…
Effective and precise fertilizing - it's all on the label
Every grower knows that the key to healthy plants is in the soil through the nutrients. A plant requires sixteen different minerals and nutrients that can be obtained primarily through the soil – with a few coming from the air collected during natural plant processes. More times than not, the soil needs…
"India’s greenhouse cropping sector and market is growing fast"
Think of a crop and you will find it growing somewhere in India, a country that occupies a massive land area over broad bands of latitude and longitude and with a corresponding wide range of climate, weather patterns and soil systems. And ‘serviced’ by a plant nutrition specialist company with such depth…
Giving soft fruit production a boost
With more sophisticated horticultural practices being adopted, the use of foliar nutrition and biostimulant products is rising. Foliar nutrition is becoming the cornerstone of a good IPM system, which is now commonplace for most growers, meaning waste is minimised and quality is improved – equalling…
Nitrogen nutrition optimization in organic greenhouse tomato through the use of "green manure"
In a recent study, in addition to farmyard manure, cowpea was applied as green manure and faba bean as an intercrop in an organic greenhouse tomato crop, aiming to increase…
Silicon compensates phosphorus deficit-induced growth inhibition in tomato
Phosphorus deficiency in soils is a major problem for sustainable crop production worldwide. Silicon is a beneficial element that can promote plant growth, development and responses to stresses. However, the effect of silicon on tomato growth, photosynthesis and mineral uptake under phosphorus deficit…
