Potato Crop Solutions

Better management of potato nutrition doesn't have to be complicated and is an easy way to improve the profitability of the potato crop. Just like any other crop, potatoes need balanced nutrition and if any nutrient is limiting or unavailable to the plant, growth will be slowed, causing a reduction in yield or quality as a result. Making sure your potatoes are fully supplied with all the nutrients they require is the best way to improve crop yield and ensure good tuber quality.

Can you really not afford to apply calcium?

Trials have consistently shown calcium can improve tuber quality by controlling or reducing a range of disorders. Specifically, calcium has improved tuber skin finish by up to 70%, reduced bruising by around 40% and shown a 75% reduction of internal disorders such as internal rust spot.

Calcium movement within the plant is by mass flow within the xylem system, which means calcium can only ever move upwards. Tuber calcium levels can only be increased by soil uptake not foliar. It is not possible for the plant to move calcium from leaves to tubers.

Solubility is the key to calcium uptake. Surprisingly most of the calcium in soil present in a form that is unavailable to plants. So it is important to apply calcium fertiliser in a form that is readily available to plants. Calcium nitrate is the most soluble form of calcium and the only fully available calcium fertiliser.

Potatoes can only use calcium when it is delivered in a water-soluble form. YaraLiva Tropicote Calcium Nitrate is the only fully soluble calcium fertiliser. Other forms of calcium are much less soluble than calcium nitrate so they are unable to supply sufficient calcium to meet plant needs.

YaraLiva Tropicote can improve potato quality

YaraLiva Tropicote is a high quality calcium nitrate product for field application. It is a dense granular fertiliser that spreads accurately up to 24 metres by machine or accurately when placed by hand. Watch the video by Yara UK Area Manager John Middleton with the key benefits implementing YaraLiva Tropicote.

What is the benefit of using Tropicote calcium nitrate rather than ammonium nitrate as a top dressing on potatoes or brassicas based on the increase in yield and quality?

Available calcium

99.5% of the calcium in the soil is unavailable to plants but 100% of calcium in Tropicote can be used by plants.

Fully soluble calcium

100% of calcium nitrate dissolves in water so it is the only fully soluble calcium fertiliser, unlike other calcium fertilisers.

Potato agronomy advice

Establishing potatoes successfully

As with any other crop, good nutrition is key to securing a healthy potato crop, one that will return good yield and high quality and ultimately achieve a better profit margin for you.

Is your potato quality being let down by a lack of calcium?

Calcium is a vital nutrient for potatoes and most aspects of tuber quality can be improved by having a sufficient supply of calcium during growth.

Increase potato yields with better phosphate management

Ensuring sufficient phosphate is available for early development is critical in potatoes so perhaps it is time for a re-think about phosphate management.

How crop nutrition affects potatoes

How to improve potato skin finish

Skin finish is important as consumers increasingly demand potatoes with clean, attractive skins. Tubers with surface infections of skin diseases are less attractive and also likely to have a reduced storage life.

How to reduce potato bruising

Potato tuber bruising is a serious problem in the potato industry. Correct nutrition of the crop prior to harvest can minimise the risk of bruising occurring with potassium, calcium and boron all having effects that reduce bruising.

How to reduce incidence of potato foliar diseases

Nitrogen applications can have the effect of encouraging foliar diseases, particularly applications later in the season which delay maturity and increase the risk of blight infection.
