Recommended Application in Carrot

BACKGROUND

Carrots grow best in full sun but tolerate some shade. In order to avoid growing deformed carrots it is better to plant them in loose soil free from rocks. The seeds, which are 1-3mm in diameter, should be sown about 2cm deep. Carrots take around 4 months to mature and it is suggested that carrot seeds are sown from mid - February to July.

In 2009, according to the Food and Agriculture Organization, 33.582 million tonnes of carrots and turnips were produced worldwide. With 15.168 million tonnes, China was by far the largest producer and accounted for 45.2 % of the global output, followed by Russia (1.518 million tonnes) and the United States (1.304 million tonnes).

PYHTOMONITORING IN CARROT

Application of various sensors for assessing plant physiological conditions is becoming a common practice in crop growing.

Recommended set-up for 5 hectars Plant sensors:

	Fruit Growth Sensors - 2 Two phenomena affect fruit diameter. These are growth and internal water content. The growth component is usually dominant. At the same time, in some cases, the fruit may loose water that is manifested in deceleration of growth rate or even shrinkage of the fruit. It may be a result of water stress, lack of light, or another limiting factor. Thus, the FI-type sensor allows investigating effect of irrigation rate and other environmental factors on both water balance and growth of fruits. Range of measurement: (7 - 30 mm, 30-100mm, 15-70mm) Resolution: 0.01mm Temperature stability: 0.005 mm/cÂ° max. Suitable fruit diameter range: (7 - 30 mm, 30-100mm, 15-70mm)
Soil sensors:
	Tensiometer Sensor - 2 Measures water tension in the soil Pipes length: 30 cm, 60 cm, 90 cm Measurement range: 0 - 84 cBar Temperature range: 0-40 C
	Soil Moisture Sensor - 2 Monitors the volumetric water content (VWC) of the soil Comes with 5cm two prong design Measurement Range 0-70% moisture
	Environmental sensors:
	Phytech's Weather station Including 6 sensors: 1. Wind Speed meter. 2. Wind Direction (optional: Leaf wetness) 3. Rain Meter. 4. Irradiation meter. 5. Air temperature. 6. Air humidity.
