BEIJING, Dec 23 (Reuters) - Chicago corn ticked up on

Monday on concern over dryness in Argentina, where corn planting

is underway, while a stronger dollar and ample global supplies

weighed.

Soybeans and wheat also gained.

FUNDAMENTALS

* The most-active corn contract on the Chicago Board of

Trade traded 0.17% higher to $4.47-2/8 a bushel at 0138

GMT. Soybeans rose 0.15% at $9.76 a bushel.

* CBOT wheat gained 0.47% at $5.36 a bushel.

* Corn planting in Argentina's top growing province Cordoba

was disrupted earlier this month by low soil humidity. Analysts

said the dry pattern in the world's third largest exporter is

becoming concerning, although supplies were ample.

* The U.S. dollar index was steady in early trade at

107.78, near the two year high of 108.54 touched on Friday,

after U.S. inflation data showed a modest rise last month,

easing some concerns about the pace of U.S. rate cuts next year.

* A stronger dollar makes U.S. crops less competitive,

compared with supplies from rival exporters.

* An anticipated record Brazilian soybean harvest pressured

Chicago soy prices.

* The U.S. Department of Agriculture on Friday confirmed

private sales of 150,000 metric tons of U.S. corn to Colombia

for delivery during the 2024-25 marketing year.

* A trade-dispute panel ruled on Friday that Mexico's

restrictions on U.S. genetically modified corn exports violate

the U.S.-Mexico-Canada Agreement, handing the Biden

administration a major trade victory in its final weeks.

* Large speculators cut their net long position in CBOT corn

futures in the week to Dec. 17, regulatory data released showed.

* Commodity funds were net buyers of CBOT corn, soybean and

soymeal futures contracts on Friday, traders said. Funds were

net sellers of soyoil and wheat futures contracts.
