Grower Reports > Greenhouse Grower
Bio-Tech Organics has worked with greenhouse growers in the Virginia district for over 22 years and have developed a system for improved production and high quality yields in tomato, cucumber, capsicum and zucchini crops, which are predominately grown in the district.

Greenhouse crops need plenty of calcium for increased flower and fruit set as well as strong cell division in the early stages of fruit development.

Most growers use calcium nitrate, however, high calcium nitrate inputs generally result in less fruit development in favour of increased vegetative growth, which can dramatically reduce yields.

There are several calcium products we favour. These include Calcium Fulvate, Calcium Shuttle, Trio, Cal-Tech and phos-Life. Liquid lime and liquid gypsum are sometimes used where these are required.

Calcium nitrate can be used sparingly in the early plant development stages combined with small amounts of Fulvic acid.

Bio-Humates versus Green Organics Compost

A recent trial comparing Bio-Humate FF50 to Green Organics Compost used by local greenhouse growers under cucumber crops, has shown significant differences in growth rates, flowering and fruit production and plant nutrient defiiciencies compared to Green Organics Compost.

From the start of the trial there was a significant difference in germination, early growth, flowering and fruit production, with the grower suggesting a 20-30% increase in yield from the Bio-Humate FF50 crops, versus the Green Organics plots.

Both plots received the same products via fertigation on a weekly basis, along with foliar sprays, the only difference being the compost types.

Photos of the two plots shows a more dense planting on the FF50 side versus the green organics side which was less robust and behind in growth and development by about 7-10 days. Leaf Colour was lighter on the Green Organics plots whilst nurient deficiencies, particularly manganese and iron, were more prominent on these plots also.

Another plus for the Bio-Humate is that it outlasts Green Organics by about 18months, before being depleted from the soil. Green organics has a short soil life of around only 5-7 months whereas the Bio-Humate, with over 300kg:ton humic acid content, lasts 2 - 2.5 years.

FF50 Bio-Humate produced up to 30% increase in yield over the Green Organics Compost.
FF50 Bio-Humate applications promotes excellent growth and uniformity in all crops. Yields are exceptional, along with shelf life and crop quality.

The result of continuous chemical fertiliser use. Soil analysis revealed 32% sodium saturation with extremely high concentrations of potassium, phosphorus, boron and chlorides. Calcium was extremely low at 42%.

Poor fruit set (blossom end rot) is generally the result of low calcium uptake. This can be caused by high soil sodium, potassium or magnesium or low soil calcium or a combination of all four.

Soil testing prior to planting is vitally important in this regard as the balance of these major cations relate directly to soil pH and the availability of essential elements for plant growth and fruit development.

Larger leaf size, more uniform colour, better balance

Biological Vs Chemical Fertiliser Trial


Local Virginia greenhouse growers TTH Do, recently conducted a trial on lebanese cucumbers to see if there was a difference between using chemical fertilisers like calcium nitrate, MKP, potassium nitrate etc and a Biological program promoted by Bio-Tech Organics using beneficial microbes, Platform Fungi, FF50 Bio-Humate, OF64 Poly Plus and Calcium Fulvate applications

Two groups of seven greenhouses were selected, side by side, with the cucumbers planted on the same day in both groups

The photos show a distinct difference between the groups, particularly on the biological side, where the plants are still producing cucumbers and will be harvested for a further 4 weeks, compared to the chemical side which was to be pulled out the day after these photos were taken.

Farm manager Phoung, commented that" the difference was obvious" and he predicted the crop on the biological side would "yield more than 30% better than the chemical side". "Getting the soil balanced before planting was a critical step for improved production, where the chemical, nitrate-based fertilisers seemed to shorten the life-span of the plants, giving less crop." said Phoung.
