Relationship between fertility extremes and growing medium pH

The pH of a growing medium increases or decreases depending on the fertilizer used, the crop grown, and the water alkalinity. However, pH change is usually gradual. When fertility levels in the growing medium are either very low or excessive, the pH of the growing medium can change rapidly. When the.....

UNH research:

Microbial traits, not plants, determine abundance of soil organic matter

Healthy soil is rich in organic matter, but scientists have yet to fully understand exactly how that organic matter is formed. Now a team of University of New Hampshire scientists have uncovered evidence that microbial pathways – not plants – are the chief originator of the organic matter found in stable.....

Effect of plant species, fertilizer on soilless root substrate pH

The objective of this study was to determine how plant species, fertilizer potential acidity/basicity rating (PABR), and fertilizer concentration affect root substrate pH. Three experiments were conducted.In the first experiment, 13 herbaceous species were grown in a root substrate of three sphagnum.....

"Bloom makes the fertilizer work better"

“We’ve tried some similar products to Holganix, but they’ve never really responded or stayed in the market long,” explains Denny Benerget, owner of Benerget Greenhouses.“When it comes to snake oil, I’ve seen it all!” With 40 years in the business, and a family ancestry spanning five generations of growers.....

Managing irrigation and fertigation on ornamental plants

At GAEC de Mezavern in Plouénan, the grower presented his 10 ha nursery. Besides the main crop of bamboo, also other ornamental plants are grown like hedge plants, Nandina, Grevilia, Rosemary, Lavatera, Viburnum tinus. Plants are grown in pots, on outdoor container fields or under shelters (bitunnel/ multi.....

New fertilizer combines nitrogen, calcium and magnesium

Calcium is essential for proper cell wall development in young plants, stems, terminal buds, bracts, flowers and fruit. Magnesium is a critical component of the chlorophyll molecule, the green pigment that creates energy for plants. Now, ICL Specialty Fertilizers’ Osmocote CalMag 9-0-0 blend is available to.....

The basics of plant respiration

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.They use the carbon dioxide (CO2).....

Pelletized soy-based bioplastic fertilizers for container-crop production

Research examining biocontainers for container-crop production has demonstrated that bioplastics made from soybean [Glycine max (L.) Merr.] can supply mineral nutrients to plants.Using soybean-based bioplastics and biochar (BC), researchers created pelletized fertilizer designed to be incorporated into.....
