Importance of data driven growing

Data science and AI technologies present us with so many opportunities to collect and mine data in the greenhouse. This paper will help you begin your journey to get the best out of your greenhouse data. There’s a bright future ahead!

The start of data driven growing

High-tech greenhouse horticulture is preparing for a new, global transition to data-driven growing practices. In Horticulture 4.0, countless sensors and measuring systems collect a constant flow of data on growth conditions and the functioning of crops, from both visible parts of the plants as well as in the root zone environment. These multiple data flows and their correlation are analysed centrally and translated real-time into setpoints using sophisticated growth models and smart, self-learning software. The recommendations can be used to maximise the expected operating results. This is the ultimate form of Precision Growing.

Unlock the potential of AI driven decision making

In today’s conditions, growing crops can be likened to performing sport at elite level. Green fingers and a passion for growing no longer guarantee good operating results. The goalposts are constantly being shifted. Stringent environmental regulations and legislation, excessive demands placed by customers, fierce competition and small margins force growers to maximise the potential of their crops efficiently and sustainably. At the same time, the continuing trend of upscaling, the tight labour market (smaller pool of available labour) and dwindling numbers of experienced crop managers (vanishing expertise) are all obstacles along the path of achieving business continuity and success. Not just today, but also tomorrow and in the years ahead.

Monitoring nutrient balance, pH & EC in the root zone

The composition of the nutrient solution should be appropriate to the needs of the crop. One of the benefits of using Grodan stone wool substrates is that the nutrient composition is under total control of growers. However the uptake of particular nutrients varies constantly with growth and fruit load therefore the nutrient balance, pH and EC in the root zone is also constantly changing.

Steering and control of EC and WC in the slab under summer conditions

How does one optimise the slab EC and WC? As the longest day approaches, keeping the slab and the crop in the proper ‘rhythm’ is necessary for peak production and fruit quality under the most stressful and demanding period of the year.

Steering WC & EC at the start of the cultivation

Starting a new crop is always an interesting time of year. It’s an eagerly awaited fresh start however some decisions and actions we make now can have a big impact later in the cultivation.

Improving tomato fruit quality

Have you ever wondered why at certain times of the year tomato crops are more susceptible to fruit quality disorders? For the most common physiological disorders namely blossom end rot (BER) and uneven colour (blotchy ripening) this whitepaper explains their cause and prescribes simple solutions to avoid / minimise risk of symptom expression in the first place.

Irrigating in changing weather conditions with minimal drain volumes

The volume of irrigation water applied per square meter is linked to radiation sum as a general rule in the ratio 3.0 ml per joule. The exact figure will ultimately depend on outside weather influences such as wind speed, humidity as well as the greenhouse vent position. The question is whether this total drain volume is necessary or not? So what is the role of drain and what is a sufficient volume of the drain?

Maintaining summer fruit quality

Maintaining a good nutrient balance along with a well-executed irrigation strategy can help to avoid many of the common fruit quality disorders which are experienced over summer. Standard feed recipes are available from all analytical laboratories and it is important that you take samples of water from within the slab on a regular basis so that the feed solution can be adjusted in order to maintain the correct nutrient ratios throughout the summer.

Optimizing nutrition to minimize fruit quality disorders

Maintaining a good nutrient balance in the root zone can help avoid many common fruit quality disorders. Standard feed recipes are available from all analytical laboratories and with a regular analysis of the root zone solution the feed solution can be adjusted so that optimum nutrient ratios are maintained.
