To address poor fruit enlargement and hollow centers in tomatoes, the following three aspects need to be clarified:

First, the duration of effective soil fertility;

Second, the timing of applying fertilizers for fruit enlargement;

Third, the correct method for selecting such fertilizers.

Only by understanding these three points and rationally adjusting fertilizer and nutrient management plans can fruit quality be effectively improved, allowing tomatoes to enlarge smoothly.

First point: the duration of soil fertility retention

The duration of soil fertility retention is closely related to soil type. Clay soils have a longer retention period, and tomatoes typically develop better fruit enlargement in these soils. Insufficient fruit enlargement is mostly related to sandy soils.

Sandy soils have poor fertilizer retention capacity and a short duration of fertility retention; therefore, in sandy soil cultivation conditions, it is necessary to apply fruit-enlarging fertilizers earlier.

Second point: Timing for applying tomato fruit-enlarging fertilizer

For sandy soils, fertilizers for fruit expansion should be applied earlier to compensate for the short duration of fertility. Considering the characteristics of sandy soils, the nutrient management plan provided later can be implemented; this plan can effectively improve the problem of insufficient fruit enlargement in the lower parts of tomatoes.

At this time, you can choose to use a combination of Monband® MBT PULI-NANO, Monband® KunKa and Monband® KaDing balanced + high nitrogen fertilizer, and adopt different fertilization schemes for different fruit setting stages.

Third point: The correct selection of fruit-enlarging fertilizer

Hollowness in tomatoes after they have swelled is often related to the presence of hormones in the fertilizer used for fruit enlargement. If the fertilizer contains hormones that promote rapid external growth, the peel will grow significantly faster than the flesh, resulting in a hollow interior.

Monband® MBT PULI-NANO is a pure nutrient-rich fruit-enlarging fertilizer, containing no hormones. It can promote the balanced development of the peel and pulp, effectively preventing hollow fruit. Combined with the calcium, boron and other trace elements contained in Monband® KunKa, it can further enhance cell division activity, improve fruit firmness and single fruit weight, and fundamentally improve the problems of insufficient fruit expansion and hollowness during the fruit expansion period.
